So I was finally able to bake my directional light maps in Blender. And the result is really good. But I cannot compare with other software so I compared with Blender Cycles and the first thing I notice is that I lose a lot of contrast. I wonder if it is a known limitation of the RNM or if there is something I can improve…
Hey Alexandr. I am trying to recreate your workflow in blender because I do prefer baking my lightmaps manually and I am used with blender. May I ask you how do you bake your basis and how do you combine them in the dot product (I guess this is the node that needs to be used at the end of the chain?) I tried to add the…
Yes I am able to boost the contrast by increasing the strength of both RNM color and normal map. Something like x2 for the colors to increase the gamma and x3 for the normals gives something very similar to ground truth:
Pretty cool. Looks like RNM is less contrasted than ground truth, based on this image from Bakery plugin for Unity (which is the baker we use). Now i couldn't tell if you could do something to improve it. https://geom.io/bakery/wiki/index.php?title=Manual
Hi folks I was trying to make a Directionality Lightmaps (Radiosity Normal Mapping) Find whis topic, but unfortunately its outdated and all the images are gone :/ : https://polycount.com/discussion/71538/how-to-directional-lightmaps-with-3dsmax-vray Currently this is what im doing: Here's my 3 basis which i use to bake GI…
I probably hadn't the slightest idea of what i was talking about back then and i don't think i messed with RNM since. Id say you need to convert your normal map from tangent to world space before the dot product. Thought i'd ask why would you want to deal with that in Blender ?
Hmm. I really struggle with understanding and dealing with tangents, so i just run a series of tests. My current test shows what i need opposite: im converting pixel normals from world space to tangent space. So basically if i calculate dot with vec3 of 0.0.1 - lightmaps looks okay* Same for textures. I use tangent space…
https://forum.unity.com/threads/baking-directional-lightmaps-with-blender-cycles.397334/ Here is a similar question with the blender setup shown, I have not tried recreating it myself and I think it is intended to be used in unity, but it might be of some help to you.
Oh crap. The colors on the https://polycount.com/discussion/71538/how-to-directional-lightmaps-with-3dsmax-vray post, are just remap to 0to1 range. I complitely missed that in description (was too tired and sleepy) and looking at 0.5 value i was immidiately thinking about remapping but i was initially calculating the…
