Beginner needs tips on vismats
-
Hello everyone,
I lately started auto-training to reconfigurate my pro life around the drawing part of architecture. I'm about ok on Acad for plans/elev/cuts, which are 90% of my work. Yet some of my architect clients ask more and more for rendered images.
I choosed skp+Vray for that, but as a beginner, I bump into several issues I can't clear through. Before coming around here, I spent unsuccessfull hours trying to find. thanks in advance for your indulgence.
- RT render : I have a GPU (in my NVIDIA quadro 600). Would I render faster with RT render (how does it work/ how to cleverly config it) ?
- Vismats : I get bad results most of the time such as image ?
Sorry for the low level of stimulation my questions might provide you, I promiss I'll improve as quick a possible.
Thank you.

1- RT is not really there yet for VR4SU. I think maybe in future releases you would be able to use RT in production rendering but for now I think most folks use it for testing and low res draft setup of scenes.
2 - Learn to create your own materials. Loading vismats, you will not learn how to control materials or how they work. This material uses displacement, which I would use sparingly. Displacement needs to applied to geometry that sits in its own group, with no other geometry.
For a beginner, I would recommend starting on YouTube at the Chaos page and watch all the videos related to V-Ray for SketchUp. Once you learn these core principals, then look into the video series from Evermotion, which has a lot of great info for the intermediate learner.

Thanks for your quick answer.
I'll sure Watch the vids you mention. If I get your tip about this material, I should check displacement. I'll do that, but indeed try and understand first how vismats work. With about a million settable parameters, I sure need method. (And humility, which we frenchies usually lack
)Merci et à bientôt / LNPT

Hello again,
I've watched some vids of Chaos group which were quite useful. I understand now the difference between bump and displacement. Tough subjects indeed for a beginner.
Am I right by saying the above mentioned issue about my crazy stonewall (image) is not a bump/displacement issue ? If so, considering that it happens a lot, leaving me no choice but to choose an other vismat, how can I avoid this obviously heavy kind of error ?
Par avance, merci.

You need to add a map to your diffuse layer so that V-Ray can get the UVW information to apply the material properly.
