    VRay reinstall

    Just thought I'd mention this... I just rebuilt my Mac from scratch after a major 'issue' with the current 10.14 Mojave system and reinstalled FormZ 8.6.3.1 and VRay build 1221 on a freshly fully formatted drive. All went ok except for the VRay install which gave the error can't find 127.0.0.1 server. I noticed that with the latest install that came direct from the FormZ site it did not ask for the chaos account login or say that it was explicitly installing the server as it installed the plugin. I did a permissions fix on the Chaosgroup folder as mentioned in earlier posts on this forum and then just downloaded the latest license server 5.1.2 from the chaos website and installed it - immediately it ran all OK on starting up FormZ. Anyway - summary - the latest license server works OK if downloaded direct from the Chaosgroup website - If like me you have to reformat your drive and rebuild your system...

    8.6 bugs

    I'm having a few repeating problems that have occurred since recent update Using MacOSX 10.13.5 - FZ 8.6.2 build 10099 and vray plugin 3.6.1 installed... The select function only in lofts and sweeps often does not take and requires me to select profiles and paths twice to get it to register. Also along this the cursor is frequently getting jammed into an enlarged size and then stays that way even when quit out of FormZ. It may be a system level issue but whatever triggers it is only happening inside FormZ.

    Render animation in vray?

    Yes it could be the system version...but this is the first time it has worked for me - after doing the last update for vray... i'm using OSX 10.13.4 Formz 8.6.2 Vray 3.6.1. here's a quick extract of the sample animation i just did which worked ok. It's crude but i just wanted to see a reflective object moving... it's a gif cause it would not let me upload an mpg. (btw i'd recommend gif brewery to any mac users for converting video to gifs ) now i'm off to try something much bigger and more complex... i'll post some samples when i get them functioning...

    Render animation in vray?

    it's working for me now too with the latest updates on the Mac. Just tried saving to a quicktime animation file and it seems to be doing the renders which are visible no vray preview grey image and no more of the save errors. I'll post a sample when it completes... and screen grab of the settings i've used.
  5. bump - any progress on adding any viable environmental fog yet?

    VRay Fur - editing gravity axis

    Yeah some of these features are things that really fill some big gaps that have been there in formz for illustration use. There are so many materials that can be enhanced using these tools if carefully applied. There have been many times that i have had to place very accurate and carefully modelled objects with very ordinary rendered surfaces into what i would consider very crap looking surroundings because i ran out of time and/or could not create or apply suitable materials, camera and lighting effects. Even if not applied to the core detailed models for a project this plugins extra tools still allow for a better visualisation context. I also have been using Formz from the early times and I think this is actually a significant improvement - especially with the speed to quality of imaging results ratio. I still see Formz as a solid and reliable modelling tool that does most of what i want to do quickly and efficiently and this just adds another layer of interest and reliability to its use for me. And there is a huge history of use of VRay out there to refer to for ideas given the range of other modelling software and platforms that also use VRay. It's just a matter of working out how it works specifically in this new software context and getting the most out of it.

    VRay Fur - editing gravity axis

    There is a lot of fun to be had playing with this that will suck up time like a blackhole... If you initially set the base length of fur very long it makes the minor changes to the variables much more obvious and easier to test out. Some of the most interesting variables to play with are the distribution - try setting it to something like 0.002 or even lower lower and see what happens. Also try setting the base size to a large number like 15 or more and the base length like about 20 and watch the cells interact. It's great for imitating organic structures and things like stone paths and foam surfaces when you do this and play with the taper. this has 0 gravity base. Also I have found that the origin surface shape makes for a lot of variation - so for example try a flat disc, a torus, a cube. a hemisphere and a twisted mesh all with the same settings and see what happens... applying it to various subdivision surfaces are also very interesting... Building fabrics with a bit of fur surfacing can be fast and sometimes more effective than just a single material fabric surface - but in combination with the displacement tool you can get some very nice effects. It can just give the objects a bit of a visual 'lift' that helps suspend visual belief... Here is an example throw rug that i threw earlier... a fabric material with furry fibres added for extra texture...

    VRay Fur - editing gravity axis

    BTW - i have had a few occasions where i have had to use the reverse normals tool on objects that have a strange geometry form and the fur did not appear because it was all inside the object. Reversing the normals will usually correct this.

    VRay Fur - editing gravity axis

    Hi - here's a quick guide... that might help get it started... create a sphere of about 2m diameter ... roughly... just not too big or too small. Add a highly visible texture like a VRay green grass ground material to it. Set the gravity to 0 leave the gravity vectors all at 0 make the base length higher than 50 add the fur by selecting the fur tool and then apply it to the sphere. do a test render and it should look something like this keep changing the length higher or lower till you can see a significant amount of fur length sticking out in all directions. If you cant see any fur at base gravity 0 then it's probably one of the other settings that is going wrong now change the fur settings to gravity 5 and change the gravity vector for Y to 1 add the fur by selecting the fur tool and then apply it to the sphere. do a test render and it should look something like this basically the gravity has to be set above 0 or below 0 to make the fur effect work otherwise it basically just has no gravity acting on it. The vector defines the direction in increments between 0 to 1 or minus 1. If in doubt just set it to -1 or 1 as you can alter the effects with the negative and positive gravity as well to get the same effect of movement as setting it to plus/minus. ie. if you set it to -1 Y then setting the base gravity to a negative number will kind of override it in part and point it in the opposite direction. so to summarise this... So you can combine the vectors to create a 3D direction - say - .2 along the -Y axis and .5 along the left axis -X The base gravity is the overall strength or pull and that can also be set to be either positive or negative or 0 where there is no pull at all and the fur just points in random directions out from the object based on collision between the individual fur objects. You can also alter the Gravity variation which defines how much each hair is randomly affected by the gravity and direction pulls. This is most evident at the point where the fur is attached to the object. You can then also alter the fur to get extensive other options in its formation and clustering. And if you try the variations for distribution you can alter the density etc. Once you have applied the fur you can edit the settings for individual objects without having to reapply it via the fur tool by right clicking on the object and editing the fur attributes directly in the object settings. hope this helps and you get some fur happening...

    Grass & foliage

    I'm interested to know how others are finding the VRay fur functions for generating grasses and landscape foliage. The results I've been getting so far have been generally OK but i'm having a lot of issues with scale and base length moving between models and projects. The shape and style of base objects seem to vary greatly in the end results they generate with overall geometry effects. eg. using a terrain, flat disc or hemisphere can alter greatly the look with the same geometry.

    VRay Fur - editing gravity axis

    Just thought i'd say that i am enjoying immensely exploring the VRay fur functions in the plugin. The axis options seem pretty good so far for manipulating the output. And there is good range of controls to create interesting variations on surfaces not just standard hair and grass... This test is a combination of surfaces to create organic cellular structures etc. I'd still like to see some volumetric cloud and fog controls though...

    Animations?

    Yep same results here. The animation window stays grey and does not show any renders completing yet progresses with the frames till the end then throws up an error primarily always about not saving. Same project will render normally as an individual frame through vray or as any other type of render style - hidden line, shaded etc.

    Animations?

    I have had similar problems. I have tried several different output methods - to individual png files and to an animation file and MOV. they all failed with a can't save the file for unknown reason type error. I will keep trying with the various settings till i get one that outputs something correctly. it's on a Mac as well.

    Swarm

    see here for the sketchup version docs - https://docs.chaosgroup.com/display/VRAYSKETCHUP/Swarm+Settings it requires a licence for every machine node still so just basically a better controlled implementation of distributed rendering with nodes...

    Glass

    Hi Dave - the mirror effect will depend on your lighting and desired overall look and feel. You will need to select a starter material and then tweak it to your situation. As this system tries to emulate real life and a mirror effectively is a sheet of glass with a metal reflector behind it you could start with either of those materials or combine them. I would start either with a transparent basic 'glass' material if you want a more subtle and transparent look and dial back the opacity and colour or 'silver polished' if you want a fully opaque reflection effect and then tweak the surface attributes for lighting effects as it is trying to look like a 'real life' metal surface. eg. Simply select a material - say the basic glass.and copy the material in the formz materials editor - rename it as MirrorGlass.vrmat and open the VRay material editor. in this case in the basic settings just change the fog colour to a full white and push the IOR up to about 10 or more and save and try a quick render. or if going with the metal - start with Silver_Polished and when in the editor play with the colour of the reflection and maybe add some white to the refraction for a secondary reflected surface effect. And if you add the two together and put a layer of glass in front of a polished silver you will get even more options to work with. here is quick render with those 3 options showing the effects with he generic provided materials Left polished silver - middle is a sheet of glass in front of polished silver - right glass only. You will need to play with the glass settings as you might notice that some basic materials use an image or grid system that ends up creating a moire effect in combination with some other surfaces. And also here are some experiments i;ve been doing with the layering of glass and materials to get facsimiles of coated and laminated glass that match industrial suppliers. I find it useful to logically combine them and get depth rather than spend time trying to make one material that does it all. Effectively what we are doing is creating a simulation of what we feel things should look like rather than what they actually look like with optical physics. These surfaces are using up to 3 sheets of glass like laminated glass or double glazing as indicated with he sample material spheres.
