Des Posted March 9, 2017 Share Posted March 9, 2017 Hi Maxwell uZers, I'm going to be working on a small bar which has some frosted glass shelves which will be backlit inside the bracket. I was wondering if some experienced Maxwell people here could give me their opinion on the setup so I can get the fastest and cleanest renders. I realise that this kind of setup could cause problems with render time and noise so really what I'm asking is how I could fake a realistic looking render. I want to be able to use multilight and not use Pshop later as I will probably have lots of images. I've modelled up very quickly a test (first attempt) to show the geometry of the shelf in which I've added an emitter (normals pointing out) just behind the glass shelf which will have a bevel eventually. Obviously I may have to add more emitters based on a gradient map which will be hidden from the camera. The attached image is a sample photo of what I'm trying to achieve. Thanks in advance, Des GlassShelfTEST.zip Link to comment Share on other sites More sharing options...
Des Posted March 9, 2017 Author Share Posted March 9, 2017 I decided to go down the route of a gradient emitter material directly onto the shelf rather than an emitter behind the glass. The two shelves shown are the same other than the top one has an unstitched edge with a AGS material to try to define it a bit more. This is my first maxwell render test so comments and advice are very welcome.. Des GradientGlass.zip Link to comment Share on other sites More sharing options...
pylon Posted March 9, 2017 Share Posted March 9, 2017 Hi Des, Can you attach your formZ project file used in the second example? Link to comment Share on other sites More sharing options...
Des Posted March 9, 2017 Author Share Posted March 9, 2017 Hi Pylon, Sure, here it is.. Remember it's just a test at the moment. Once I get it right I'll place them into my main model. Thanks, Des GlassShelfTEST.fmz.zip Link to comment Share on other sites More sharing options...
pylon Posted March 9, 2017 Share Posted March 9, 2017 Hi Des, There are a number of other mxms and bitmaps missing; can you do Workstation Transfer and include all dependencies? Link to comment Share on other sites More sharing options...

pylon Posted March 9, 2017 Share Posted March 9, 2017 Hi Des, I adapted your unstiched edge strategy. Edge now assigned an autotranslated "frosted glass" material. I put an additional emitting plane in the rear to illuminate the frosted edge. Finally, I adjusted the "Burn" parameter down to 0.05 to avoid blown highlights. Hope this helps.

Des Posted March 10, 2017 Author Share Posted March 10, 2017 That's excellent Pylon. Thanks SO much for your time on this, the edges look exactly how I'd expect. Link to comment Share on other sites More sharing options...
pylon Posted March 10, 2017 Share Posted March 10, 2017 You are welcome Here's another approach. It's more realistic, I think. Shelves_3.zip Link to comment Share on other sites More sharing options...
Des Posted March 11, 2017 Author Share Posted March 11, 2017 Thanks Pylon, It most certainly is more realistic and I see you've placed strip emitters to accentuate the light to the wall. The amount of frosted glass is slowing up the render I think. I'll wait until my main model is more advanced and then decide which approach to use after I test the benchmarks of each. Thanks again for all your help Pylon. I hope others have learned from this too. Des Link to comment Share on other sites More sharing options...
