Member biscuitguy Posted April 12, 2017 Member Report Share Posted April 12, 2017 Hi there, I'm trying to bake my sculpt model to low poly mesh by "Bake w/ Normal Map (Per-Pixel)" but baked maps has strong noises on any Materials. this is sculpt mesh. (sorry for poor mesh, this is my best.) and this is baked mesh on Paint room. diffuse and normal map have strong noise.. (it should say dithering?) what happen on my 3d-coat? I'm using ver4.7.26(GL) Alienware 17 R2 w/windows8.1 64bit thanks, Quote Link to comment Share on other sites More sharing options...
Carlosan Posted April 12, 2017 Report Share Posted April 12, 2017 Hi ! Show voxels in paint room is = off ? Quote Link to comment Share on other sites More sharing options...
Member biscuitguy Posted April 12, 2017 Author Member Report Share Posted April 12, 2017 Hi, Carlosan. ya, voxels is hide on Paint room. I tried another file or simply voxel, but I got same result... Quote Link to comment Share on other sites More sharing options...
Carlosan Posted April 12, 2017 Report Share Posted April 12, 2017 The texture resolution is low ? How is packed your UVmap ? Bake normals with dithering is = ON ? Quote Link to comment Share on other sites More sharing options...
Member biscuitguy Posted April 15, 2017 Author Member Report Share Posted April 15, 2017 look like resolution was not affect to noise. (but size is change) and UV also not affect. (I tried copy and paste as maximum scale to new UV a piece of mesh) Bake normals with dithering, I tried both, but seems like no effects on my mesh. I tried export voxels and retopo meshes to new scene, but it happened again. totally no idea. Quote Link to comment Share on other sites More sharing options...
Advanced Member gbball Posted April 17, 2017 Advanced Member Report Share Posted April 17, 2017 I had this problem also. To fix it you will have to adjust the normal intensity on your pbr sculpt shader. For some reason the bake results are really strong compared to what you expect. I think it has something to do with the way the shader resolution is tied to the density of of the sculpt layer. Anyways, if you turn down the bumpiness on your shader it should give you better results. You can also try adjusting the texture scale to see if that helps. Reducing 'bumpiness' value prior to baking should do the trick though. Quote Link to comment Share on other sites More sharing options...
Member biscuitguy Posted April 17, 2017 Author Member Report Share Posted April 17, 2017 hi, gbball. surely I changed scale voxel mesh. now I lend to colleague my laptop whose install 3d-coat, so I'll check shader after she is back. Quote Link to comment Share on other sites More sharing options...
Advanced Member gbball Posted April 18, 2017 Advanced Member Report Share Posted April 18, 2017 (edited) Sorry, to be more clear...you'll have to right click on the pbr shader you're using for the sculpt object and adjust the bumpiness setting on the shader...you don't need to change your sculpt resolution.

Member biscuitguy Posted May 3, 2017 Author Member Report Share Posted May 3, 2017 hi, seems like this problem has solved by voxels scaleing up size to 1000%. it means my sculpt voxels was too small. not 3d-Coat's problem. (ya, me also could sculpting and baking before.) thanks gbball and Carlosan! 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member gbball Posted May 3, 2017 Advanced Member Report Share Posted May 3, 2017 Glad to hear it worked out. Scaling up the model should have the same effect as reducing the objects density, or adjusting the settings in the scale/bumpiness in the shader since it seems like the shader info is tied to the object density per layer. I notice it because I change density on my sculpts a lot and it causes problems when I bake with certain shaders. 1 Quote Link to comment Share on other sites More sharing options...
Advanced Member Hammers Posted November 4, 2017 Advanced Member Report Share Posted November 4, 2017 (edited) I'm having this issue baking to the paint room too. My shader in the sculpt room isn't even using normal/bumpiness. So I don't know what gives... Edit: Trying with Bake update to Paint Layers, seems to work better, Bake w/ Normal Map has same problem ie. noisy normals.
