Advanced Member arumiat Posted January 13, 2015 Advanced Member Share Posted January 13, 2015 This was an interesting thread to come across. I was a bit taken aback the other day when I brought a model into Blender from 3DC and opened up the node editor to find this. I was sad to switch to rendered shading and the 3D coat material to not display but is there a way to recreate 3DC materials within Blender then? Are they based on the same/ similar underlying 'nodes'? Quote Link to comment https://3dcoat.com/forum/index.php?/topic/17212-pbr-in-blender-cycles/ Share on other sites More sharing options...
Carlosan Posted January 13, 2015 Share Posted January 13, 2015 Hi There is an experimental shader, if you like to try https://jtheninja.wordpress.com/2014/09/27/blender-cycles-simple-pbr-shader/ And there is a Blender branch http://blenderartists.org/forum/showthread.php?343278-GLSL-PBR-Shader-for-viewport Quote Link to comment https://3dcoat.com/forum/index.php?/topic/17212-pbr-in-blender-cycles/#findComment-117341 Share on other sites More sharing options...

When I checked the second link I noticed there was an update to PBR_SHADER 1.75 for Blender 2.73. https://matthieubarbie.wordpress.com/2015/01/12/pbr_shader-1-75-for-blender-2-73-documentation/ 2 Quote Link to comment https://3dcoat.com/forum/index.php?/topic/17212-pbr-in-blender-cycles/#findComment-117369 Share on other sites More sharing options...
Contributor Malo Posted January 14, 2015 Contributor Share Posted January 14, 2015 (edited) My understanding of shaders is limited. Is there a way to create material in Cycles that will work in 3DCoat? Thats why we post some links for you. You only need the model and textures from 3d coat, there is no need to understand the nodes compledly in cycles. Simple put your Albedo, Normal, Metallic and Roughness maps into the right slots and hit render, thats all. But no, there is no way to create a Cycles material that works in 3d coat, or in the other way. Both use its own shading and material system.

Reputable Contributor digman Posted January 14, 2015 Reputable Contributor Share Posted January 14, 2015 (edited) These settings I find so far work best for me exporting out of 3DC and using the Dual PBR shader in Blender. GGX shader under the view window in 3DC for rendering in the 3DC viewport. In Blender the Dual Shader uses the Ashikhmin-Shirley distribution setting and not the GGX in the Glossy BSDF Shader. I have not tried setting the dual shader to GGX under the Glossy BSDF. Export Roughness and Metalness in the export settings panel. Blender: Dual Shader, selection of course is Metalness and Roughness. The above appears to get me best match of the Teapot of what I see in the 3DC viewport and when I render in Cycles. This Gloss (roughness) and Metalness setting from the 3DC export panel, the Gloss (roughness) map did not work nearly as well as the Roughness map... The above is all a learning in progress and open to change but so far that seems to work out the best. PDF Link to the Ashikhmin-Shirley Microfacet-based BRDF Generator http://www.cs.utah.edu/~shirley/papers/facets.pdf I am not a math major by any means but general principles on what they created is an interesting read... By the way thanks for the Links Malo...

Moderator Daniel Posted June 4, 2015 Moderator Share Posted June 4, 2015 Guys, help please! What are the Normal Map correct presets in 3DC 4.5 to Cycles (I can't get correct normal map appearance) Thanks a lot!

Contributor Malo Posted June 4, 2015 Contributor Share Posted June 4, 2015 Didn´t the Blender Preset while baking /w normalmap work? What are the problems in Cycles?

Member pengo Posted June 10, 2015 Member Share Posted June 10, 2015 I have also problems with the normal map with the PBR Shader Vers. 1.75. It gives in some areas (were shadows should be) very dark and sharp shading results. With the dual shader it does not happen, but i don't have then the shiny shading results, the surfaces look matte then.

Moderator Daniel Posted January 26, 2016 Moderator Share Posted January 26, 2016 Guys, I think I've made a Complex (but with simple inputs) PBR shader for Cycles based on this guy's videos I guess it is a kind of similar to Simple PBR v4, but a bit different These are screenshots from 3DC viewport and render with cycles (with black background) What do you think??? P.S.

Moderator Daniel Posted January 26, 2016 Moderator Share Posted January 26, 2016 Key thing is playing with RGB curves for Roughness map (Color or Non-color data), for Metallness map I found Non-color data work more closely to what I see in 3DC. Anyway, need your tests! P.S. Shader is very cool for working even without textures! 2 Quote Link to comment https://3dcoat.com/forum/index.php?/topic/17212-pbr-in-blender-cycles/#findComment-131038 Share on other sites More sharing options...
