This option tries to blend the edges of the displaced model to a continuous geometry and is very useful for applying displacement on all kinds of 3D shells as opposed to 2D surfaces. The 2D displacement mode lacks the setting “Keep continuity” which 3d modes have. It’s a very efficient mode of V-Ray displacement and it is commonly used as a method to create all kinds of flat surfaces like ground, grass, pavements and ground tiles. The displacement map can take any values. You cannot use this method for 3D procedural textures or other textures that use an object or world coordinates. However, it requires that the objects have valid UV coordinates. The advantage of this method is that it preserves all the details in the displacement map. The actual raytracing of the displaced surface is done in texture space, and the result is mapped back into 3D space. The displaced surface is rendered as a warped height-field based on that texture map. 2D mapping – Bases the displacement on a texture map that is known in advance.Delete unnecessary geometry or change it to bumpĢD displacement (Landscape) according to the V-Ray manual:.Subdividing the mesh for better RAM results.A tip for rendering closed 3D objects with 2D displacement.In this part, we will talk about 2D mapping (Landscape) displacement and various techniques that help cut down on resources (mainly RAM), while rendering scenes with V-Ray displacement. In our previous guide about displacement maps, we talked about the standing theory behind V-Ray displacement and found ways to optimize the settings for the 3D mapping displacement mode. I feel that my Normals don't work either, my model looks completely flat!ĭoes anyone know the solution to this? I am tempted to just use Mental Ray and get on with it.How displacement maps work and how to optimize them in V-Ray - part 2 Introduction I've turned on the Displacement in the RT engine, the Displacement Map in the MeshShape is also on, Displacement Control is also on. One of my friends couldn't see the problem, but I can clearly see that the curves in my Mental Ray alpha are not visible in the VRay alpha. I can see that it's having an effect on my model (the face puffs up as I up the Alpha Gain in the displacement map) but it doesn't smooth out my edges. I began my project by using Mental Ray, in which everything worked well, and then switched to VRay under recommendation and I can't get my displacement maps to work. I am having problems with rendering in VRay.
