Try the demo of both and see which you prefer. Which to choose depends on many things. Cost, workflow your knowledge level of rendering, time to learn, setup times, etc.

I'll sometimes copy the offending object into another file so that i can use this feature to find my mistakes without messing up the materials.

@ithil said: Yes. This option is really necessary. Maybe solution to the problem can be of a button "turn off/on subdivided" for all subd-objects in file. We can turn off all subdivided objects before saving. And turn on after reload. That could be a useful function, indeed. I'm logging a feature request for that.

I'm only a novice at Vray, but it seems that the only way to get a numerical value for the roughness is to create a new "Vray material" from scratch. Here's the manual description of how to control it: https://docs.chaosgroup.com/display/VRAY2SKETCHUP/VRayMtl#VRayMtl-Diffuse

I would do this using Curviloft by Fredo. That way you can easily control all the cross sections, contours etc and let the plugin do the work for you. http://sketchucation.com/forums/viewtopic.php?t=28586

@peerman said: For a studio environment you can use an HDRI with a studio image. There is also the vray express installer which has studio environments for Sketchup. It gives you components with standard light setups and studiomodels. You can find it in the download section on the chaosgroup website (you have to log in). For some free HDRIs you can google. I have found this one.. http://zbyg.deviantart.com/art/HDRi-Pack-2-103458406 Maybe there's something for you in it. Best Thanks a ton for enlightening me about something sooooooooo amazing that I never knew! I was blown away by such HDRI envrinments! Seriously WOWWWWW! I'll surely try them out and post the renders here. I don't have have appropriate words to express my excitement and gratitude for this link. Thank you so much.

Why not use the free Visualizer? [image: 44aK_why_no2t.jpg]

@rspierenburg said: Try increasing the "Normal Threshold" in the toon material. That made it! Thanks a lot. I set it to 0.99

Hi, what are your settings for the background? Is it from the vray sun or do you use a domelight for the background? If you use a domelight make sure in the options to check the reflection on. Best,

Or maybe use a blend material? With material A being the tile material and the B material a procedural noise for instance. Haven't experimented with it yet. Best,
