We will talk about them at the end of the guide.Īccording to the V-ray manual, there are three types of mapping in VRayDisplacement Mod: Performance and other settings – These are special settings that affect rendering performance they can be used in rare scenarios for debugging displacement-related issues, like artifacts or unusually high resources usage.
They are decisive in the number of resources your scene needs for rendering, and we will optimize them in the next chapters of the guide. Quality settings – These set the displacement’s level of detail, number of subdivisions, and mesh density. Please turn to the other settings listed below instead. Therefore, these values should not be compromised for the sake of optimization. They need to be set to specific values to get the exact look of the displaced model you want. Using the VRayDisplacementMod modifier provides more flexibility in setting up displacement features and managing resources necessary for rendering.ĭisplacement features settings – These influence render times and RAM used by the scene. The downside of this method is that it can create very heavy meshes that require a lot of RAM to process. It does so by dividing the model’s polygons into a much denser mesh during the rendering process, which is either elevated or depressed on an up/down axis based on your chosen texture. It’s thus mostly used in computer games to add detail to models while keeping a low polycount.Ĭontrary to those methods, displacement mapping creates real 3D geometry it casts real shadows and looks realistic from every angle. Like bump mapping though, the effect is purely based on rendering it doesn’t add real detail to the geometry. It does the same job as bump mapping, except the details are created based on an RGB color map that encodes the angles of the surface. There are cases where it doesn’t look all that convincing.Īnother method is the normal map (normal bump).
You wouldn’t, for example, see changes to the contour of the object. It does the job for small, finer details, and only in some angles. Instead, it creates an illusion of 3D, “faking” it during the render process by having light bounce off simulated features that are not actually there. However, bump mapping doesn’t create a real 3D structure. By taking the placement of light on the model into consideration, it imitates a sculptural relief on the surface, portraying shadows and highlights to simulate texture and depth. Given this all-important feature in real surfaces, 3D applications quickly incorporated tools in their material editors necessary to generate such an effect. It’s this essential trait in materials that make them look interesting and real. Each surface contains a 3D structure through which, slick or rough, we perceive texture by how light bounces off its bumps and scratches.
Easy to resolve if you try the original trial version with a dummy account.It’s not only color or reflection the 3D surface of the material also needs to be reproduced for a realistic look.įirst, let’s have a look at how displacement works as opposed to bump and normal mapping.
If so, I don't see how they could have messed up with this but maybe they transferred a too-old crack to this version. If none of the above applies, you could have a bad crack. According to your image, it looks like it crashed just when it started. If you have installed only the Freebie, then there shouldn't be any sync problem and the error lies elsewhere.Ĭheck for any vray logs. You could have a conflict between the plant and its Browser (out of sync versions). It should show the materials that came with the plant (see the image I posted). When you load the plant, open up Vray's material editor. If the Freebie, which version? I used one that was installed with one of the Plant Kits but I see they have a new one on their site (you have to supply some dummy info and I didn't have the patience for it). Is this only with the Freebie Kit or have you tried some of the other ones that have been posted?
