Bump is going to be very reactive to the direction of the light that is shading the surface (since bump changes the normals of the surface), so in a pure GI type environment you won't really see the bump effect that much. So everything i would like to insert a tree or people in my model, do i have to insert the image -> explode -> make component -> make face me -> make a new material with the external material editor an apply it to the people/tree? It has to be an easyer way.Ĥ- Is there any way to preview Vray materials when we choose them (i mean all of them like in sketchup, not clicking 'Update' in each of them) Why happens that? it's like vray couldnt modify sketchup linked material to make displacement or something like that. With Bump & Disp nothing happens, but when i render the model with clip mapping it works.Īpply material in sketchup, link with Vray and modify with alfa:Īpply material in sketchup, make a material in external editor an aply later to the object: That way, the vray material adopts U and V coordinates of sketchup. I apply that to the object that had a sketchup material on. In sketchup, i import new material and choose the one i have just done. Then i create a new material with the vray external material editor using the same texture for difusse and a grayscale of that image for displacement. And same with clip mapping (transparent).ģ- So, i tried another option: I apply a material in sketchup to a model. Well, at that point if i render the model with an vray light above the object(gi_irmap_medium.visopt) everything goes right, but without the light there is no bump.Ģ- If i use the same grayscale image in displacement channel (and uncheck bump) and render the model, nothing happens, there's no displacement (although in the update preview the material it show displaced material perfectly). So, to add bump to that material, i create a new VrayLinkedMtl and i apply a Bump image in Bump channel. Nevertheless, i have some problems, and i would be very grateful if someone could help me.ġ- When i apply an sketchup material to an object and i render, everything goes ok. Until now i rendered my proyects with kerkythea, but i preffer vray. I'm studying architecture and i've been using sketchup for over 3 years.
