Hello Achim,
would it be possible to share the project file and project folder with us, only with the one model that is textured and that is causing problems so that we can test it on our side?
You mentioned that you were able to create an ortho projection in the same project in the previous version. Have you tried to create an ortho projection from the same singleton model with the same number of textures?
I believe that the issue with this particular model is same as mentioned here:
https://support.capturingreality.com/hc/en-us/community/posts/360002159452-Bug-11580-Orthoprojection-Memory-Issue-latest-build-RC-
You have one singleton model with over hundred textures and RC is loading all the textures when creating ortho projection at once. That is the reason of the large memory consumption.
In the meantime, you can try the workaround proposed also in the thread mentioned above:
- Import the model and change in the RECONSTRUCTION - Settings - Model import the ‘Maximal vertices count per part’ to a smaller number so that model will be divided into parts and unwrap and texture the model again. Or if the model was created by simplification, change Preserve parts to ‘True’ in the Simplify tool settings and again unwrap and texture.
You should be able to create an ortho projection without problems.
