![]() ![]() IIRC, bump maps have to be calculated 3 times (for x, y, and z)ģ. Normal maps, also known as "dot-3 bump maps" are basically the latest version of bump maps.Ģ. Bump maps contain only height info, normals can have any angle. ![]() I like normals, especially object & world space allow cool animations like raindrops sliding down. So for 'ground truth' rendering I'll always take better memory management & efficiency VS fake options.ġ. This example clearly shows what waste, confusion & time consumption it makes while giving no true benefit. Bump & displacement are more than enough. Yes, i too noticed that c4d noise doesn't get through Normalized shader function into Corona Normal (other c4d procedural textures work fine) & as i wrote, i never use normal maps in unbiased, especially spectral engines. Unfortunately, the normalizer doesn't work with all types of noises or they have to be "hidden" inside another shader, but the normalizer would be the correct way. Similar to rotating the vertex normals too much. The only thing that you get without additional bump is some fake shine on the surfaces because the engine assumes the polys to be in some weird position. all the swapping doesn't help if you don't have RGB lit noises. ![]() The additional bump channel is strong enough to take over the most, but it's still noticeable. The last version with standard noises plugged into NRN is clearly wrong. IPR first starts to show only raw, flat shaded geometry and needs to be restarted or after a while, Cinema crashes.įile in OP uploaded, updated with Corona Normal shader in Bump channel of Corona Material: noisetest_B2.7z Normal maps are intended to fake light distribution over surfaces (bumps & dents), enhance low poly geometry & in RT game engines.Īs i had IPR running & developing shaders with Corona Normal shader in Bump channel,Īfter almost every 3rd/4th time the change to shader was made (specifically: swapping RGB channels direction), Imho, it's nonsense, an oxymoron & their use in such way is more problematic than helpful :p ![]() I guess - cuz i never use normal maps in context with physically accurate/unbiased rendering (light transport simulation) updated the file with Corona Normal shader version in Bump channel. Have you had any luck using a normal texture map in the bump channel via the Corona -> Normal option?
