    Point lights

    Yes, I always aim a plane light by translation only. I seem to recall lights acting strangely if I used the pointy end or any other means to aim a light. Usually the plane goes in a window or up on the ceiling. I use the standard rotate and move tool looking from the two angles. I do have to type in the size of the plane in the properties. I only use translation tools to aim IES lights too. Just makes it easy. Of course, sphere lights don't have aiming issues which was part of the ease of use. I never use cones. It is probably easier to build the correct geometry and assign an emitter material or do mesh as Andrew does, now that I write out my process. Mine is just the old RZ way.

    Sorry, the resolution on the posted image is too low. It is really 5000 pixels wide, the moire patterns are not there.

    Last image I did last week. I did stray from VRay spheres and used IES for the lamps. One VRay plane light in the ceiling. There is an emitter material on the screen map. All modeled in formZ and rendered in Vray.

    Point lights

    Hi Cobrien, I wanted to share my easy lighting Vray workflow, at least for interiors. One thing first, point lights are bad because in the real world, light never comes from a tiny speck. If it did, you would see bizarre shadows. Light always comes from a surface that has a size, and this makes shadows get blurrier at the edge the farther they are from the subject. Natural shadows are one of the most important for nice renders. SO, Andrew is right, mesh lights are the correct solution. I cannot bring myself to this, I don't know why. I only use the VRay plane light, and the VRay sphere and keep the old workflow. I put the plane lights in the windows, using the translation tools (not the light controls). I throw the VRay spheres in for fills and even general illumination. I make the lights invisible, and hide them form reflections as needed. I turn the plane lights down to 5 (they start at 30), also the spheres. One nice thing about this method is the values for the intensity make sense and respond to intuitive numbers. Plus once you have one set up, you just duplicate them and move them around. This gives you the old feel of working, but the advantage of the VRay render. I find I do the same in Arnold.

    Why form•z is not popular any more:

    While you all are mentioning it, my company gives me that AEC suite from AD. And Maya and the engineers use SW. Nice, but in practice, formZ is basically the "brain" program for an octopus of functionality. I do just about everything in formZ, then if I need Revit, for Families, I go there. Need Maya, no prob. Even bring in Solidworks with STEP to make Revit Families. I think the reality of today's work is that you need various apps, but I still find formZ a clear winner for the returns. At least in the manufacturing world, I don't know how someone would do this without formZ. If someone is sitting there trying to do what I do without it, they would be spending a criminal amount of time working with slower tools and doing many more workarounds. The money being saved in this context is substantial. All models accurate and solid! formZ is truly a jewel in the crown of apps when real work is concerned. It's proper place may be in that AEC suite. It works very well with it. BUT, the idea behind the AEC package is you wind up paying a big yearly fee to these other guys. Past what a freelancer could do. Using those programs, though, and living in the real world, it becomes clear that you need to be able to use whatever end result program you need for whatever project you have. Notice the focus on making a certain amount of income. It is actually very nice to have a niche place right now where you can still get permanent software and individual attention. The price for the support is very very reasonable. As far as interface, I have used them all and done real projects and they all have their downs. They also all have forums where somewhere, folk complain about the interfaces. formZ came from an altruistic pedigree that is different than the commercial giants out there. If there was a humanitarian project in which formZ was needed, formZ was provided for those at no cost. The creators of formZ started as educators and have never been focused on income. They have always been primarily concerned with what we design and build with formZ. That's what they have been watching. There used to be a very formal architectural forum/blog that would have articles on new buildings, and if formZ was mentioned in the article as one of the apps used, it was included in that particular thread. I can't find this now for the life of me. Does anyone remember that too and know where it is? That blog was always awesome because there were all these new and wonderful buildings that used formZ in the design process somewhere. It was very inspiring.

    Isn't this tool and it's options what you are posting about? If not, sorry.

    First Project with Twinmotion

    Nice Des! Thanks for sharing your Twinmotion project, it is great to learn from others to put in the mental bank in case needed. As far as the boxes, here in Columbus, Ohio, just about everything looks like that! John A

    Project Lavina Support

    Hi Anwar, Thanks for asking this, I need this ability too and didn't know about this. This could be it, except I need to put the controls in the clients hands. I already have the RTX card. ADS can we do this? They are asking for a VRay scene? Thanks, John A

    + Light

    I'm glad the lights showed up. I do seem to recall needing to really use large values on lights in Maxwell.

    + Light

    Hi Bo, I have not had Maxwell in a few years now, but if my terrible memory is correct, and you may not believe this, but the model was to make geometry (read light bulb) and assign an emitter material. It was a totally different way of doing it. Maybe this isn't right. They would need a way to assign IES lights. Does someone still have Maxwell?

    fZ + Python + CO2

    That's great! Bed size is reasonably large too. I used to be able to cut stuff when I worked in a sign shop. Gear heads that worked there would even make their own gaskets in a pinch. We only used .dxf for getting the path into the path cutting software. It was some time ago. Interested to see what you do with this!

    Way to animate the move multi-copy effect

    Hi Chris, I think it can be done or something similar in several ways. Actually now that I write this and really rack my memory Mathew Holewinski has outlined a way to use animate along path and extract animation to do something quite close. He made a series of wooden bollard things that went around the edge of a garden path. He even had them getting a variable angle so they wobbled randomly. This was just with the tools. I probably should have done that method without the wobble. I was working on an animation yesterday, where the client wants a wall framed in an animation. Actually the product is a door, so the wall construction animation is not the point. My animations now need to be done so fast I have to show vertical studs fading in, which is just rendering a still and using After Effects to do the fade. I was thinking it would have been so cool to be able to pull off the studs sliding into position in the same time frame. I have never learned scripting (I sat down to do so at least 3 times in my life) the problem is can see it's value, but I am always full with busy work and never get any bang for the buck in the first week and I notice 3 weeks later I am not still working on learning it. I did do Basic and Pascal in the eighties, HTML in the 2000's and that's it. It has always been easier for me to bull through something, for example I would sit and key all the studs flying into position. This was making my animations take too long to produce--doing something more visually interesting when maybe the script or budget can't support it. A script that emulates key-framing the move multi-copy is one simple animation/script idea that would save time. But, path animation may be quite sufficient. Another would be a canned "exploded" view animation, where parts of an assembly all fly out to a certain distance, and then fly back. But alas, these are just those dreams that come as I hustle through a project. Just a strange side question, did you ever make your own balloon? I sometimes wish I could make some sort of cool flying personal dirigible, but I am afraid of heights.
