Advanced Member Skye Posted June 19, 2018 Advanced Member Report Share Posted June 19, 2018 Hello, I encountered strange behavior when importing external mesh for retopo. It is a simple pipe, so low poly model as a retopo cage and turbosmoothed hi poly model. When I bake them all normals are flat, no curvature informationi. But If I import high poly model into sculpt room and subdivide and then bake with cage, normals are properly baked. Am I missing something in retopo settings?

Carlosan Posted June 19, 2018 Report Share Posted June 19, 2018 Sorry but, low poly model have uvset, right ? Quote Link to comment Share on other sites More sharing options...
Advanced Member Skye Posted June 19, 2018 Author Advanced Member Report Share Posted June 19, 2018 Yes, I did uvs for low poly and then baked Quote Link to comment Share on other sites More sharing options...
Carlosan Posted June 19, 2018 Report Share Posted June 19, 2018 The normals are ok ? Quote Link to comment Share on other sites More sharing options...
Advanced Member Skye Posted June 20, 2018 Author Advanced Member Report Share Posted June 20, 2018 This is how it looks like. Quote Link to comment Share on other sites More sharing options...
Contributor Tony Nemo Posted June 20, 2018 Contributor Report Share Posted June 20, 2018 Your import to Sculpt saves all relevant info and is the correct method to use when wishing to change the topology. I am not familiar with"turbo smoothing" but it may have been involved in your problem. Quote Link to comment Share on other sites More sharing options...

Advanced Member Skye Posted June 21, 2018 Author Advanced Member Report Share Posted June 21, 2018 Thanks for your replies guys, of course If I import mesh as in video, normals are baked properly. But If I go from retopo menu as you see below or File -> Import -> Reference mesh, I will get baked flat normals. Basically there is a low poly pipe that I turbo smoothed to get High poly smooth object that I used as high poly reference, then I used the same low poly pipe as a Retopo mesh or cage, to bake normals from that HP obj.

Carlosan Posted June 21, 2018 Report Share Posted June 21, 2018 Ah ok, Reference mesh is only for... Reference. please check this On 7/18/2017 at 4:16 AM, digman said: Example of one Workflow: It is just an example that is all, as I said there are several methods. I have a hard surface high polygon model created in Blender and plus have the low polygon model of the same model created in Blender. I would import the high polygon model into surface mode, not voxel mode. Not explaining here about surface mode or the reason of using it in this example. Next I would import the low polygon model into the retopo room for my retopo mesh, then create my uv seams and uv set. Bake to the paint room to create the normal map details from the high polygon model in the sculpt room. Texture in the paint room and export for Unity 5 or Unreal 4. TIp: To import a low polygon model into the retopo room to be used as your retopo mesh: Retopo Room---Retopo Menu---- Import. You will be asked to snap the retopo mesh to the reference object in the sculpt room. To say yes or no depends upon the your retopo mesh. I generally say no and do any local adjusting by hand if needed. Quote Link to comment Share on other sites More sharing options...
