Carlosan Posted January 17, 2016 Report Share Posted January 17, 2016 Paint Room Import model for PPP When i import a model all the materials are listed as UV set names The original exported model have 6 meshes and 11 materials After import i have 6 paint objects but 11 uv sets. The original model have only 1 uvset by mesh. Total = 6 uv sets - File format export dont matter, obj, fbx, dae... - Preferences > Treat retopo objects as Paint Object dont matter, this option on/off change anything When exporting textures i have 11 normal maps, 11 reflections maps, etc What workflow i need ? Be able to import a model made by different meshes, and to use for every mesh their own original UVset. To have automatic group layer created by mesh, but inside every layer group to have for every material a layer created and named. Export only texture maps by paint objects, not for every material Whats im doing wrong ? cant achieve this workflow Any help is appreciated. ty Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted January 17, 2016 Reputable Contributor Report Share Posted January 17, 2016 (edited) Hi Carlosan, is it possible to share the blender file through a private pm or link where I can download the blender file to test for a workflow.

Carlosan Posted January 17, 2016 Author Report Share Posted January 17, 2016 Hi Digman Im waiting to test the new version 4.5.27 first with 26a got better result using .fbx extension, uvsets are listed ok... but 3DC freezes at import.

Carlosan Posted March 3, 2016 Author Report Share Posted March 3, 2016 Still trying to find a workflow obj, fbx dae... 3DC > import model for ppp > all the materials are listed as uvset suppose i have a model with 3 objects: cube, sphere, cone every model have their own uvset and materials: cube, sphere, cone Thread retopo objects as paint objects = ON When i import the fbx model for ppp there is 3 paint objects, 3 surface materials, 3 uvset When i import the obj model for ppp there is 3 paint objects, 3 surface materials, 3 uvset Thread retopo objects as paint objects = OFF When i import the fbx model for ppp there is 3 paint objects, 3 surface materials, 3 uvset When i import the obj model for ppp there is 3 paint objects, 3 surface materials, 3 uvset IF i add a new material to one object, example i a ssign a new material to one cube face... When i import the obj model for ppp there is 3 paint objects, 4 surface materials, 4 uvset why ? i still have 3 uvset, one by object... not 4 im lost 3.zip Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted March 4, 2016 Reputable Contributor Report Share Posted March 4, 2016 (edited) Yes, the way models are imported into the paint room needs to be updated... 1. multiple objects in the same file with multiple surface materials and uv sets.. 2. Imported so each object will have it's own paint layer group which includes the surface materials and the uv set for that model. The above is I believe is close to what you are asking for, correct me if I am wrong..I might know a workaround but would have to test and it would be rather a lot of work... The importing of models into the paint room does need an update... Once 4.5.29 with the new PBR system is completely working, would be a good time to address the issue to Andrew... We could combine our ideas on the matter... I will look at your file too... Edited March 4, 2016 by digman 1 Quote Link to comment Share on other sites More sharing options...
PolyHertz Posted March 4, 2016 Report Share Posted March 4, 2016 OBJ format does not natively support more then one UV set per-mesh, but can have multiple material per-mesh...I guess it was implemented in such a way due to that limitation? I do think it would be nice if there was a right click option on layer groups to export just the groups maps though. Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted March 4, 2016 Reputable Contributor Report Share Posted March 4, 2016 (edited) The OBJ file format though can support more than one UV set per mesh... 3DC will recognize the multiple uv sets for one mesh in an obj file.. See attached image. It has to be written a certain way, I have not studied enough to know yet... The cube in my example had the two uv sets created inside 3DC and exported from the retopo room. I then imported the cube into PPP mode in the paint room It is a simple cube with two uv sets and a surface material associated with each uv set... This imports into 3DC correctly as one model with 2 uv sets and a surface material for each uv set. If I misunderstood your statement, then please inform me.

Carlosan Posted March 5, 2016 Author Report Share Posted March 5, 2016 The FBX models exported from Blender 2.76 import into 3DC with no problems. TY, im testing that so Quote Link to comment Share on other sites More sharing options...
Reputable Contributor digman Posted March 5, 2016 Reputable Contributor Report Share Posted March 5, 2016 (edited) TY, im testing that so That statement of mine was concerning the visual appearance of the imported Modo FBX file, not concerning how it imports uv sets and materials. His FBX model had visual artifacts. I updated my post in the SOS thread to reflect what I just said here...

Carlosan Posted March 5, 2016 Author Report Share Posted March 5, 2016 The obj model exported from Blender 2.77 import into SubstancePainter show the same problem. 3 models but 4 uvsets obj file system = no good im rethinking my workflow, i need to import/export one model with some subobjects without troubles Quote Link to comment Share on other sites More sharing options...
