Previously most of my models were limited to WSF. I build models to tight tolerances and ones designed for WSF have some walls at 0.7mm thick. Recently I have noticed that the material limitations I had added have gone, I don't know when this happened. Now many WSF have been made available to print in materials that they won't.
Do I need to manually change this or is this some sort of bug?
About 2 months ago (when we introduced the milky white glass material) the working of the material restrictions was changed. All restrictions should have been migrated ok. Please note that the materials listed as 'restricted' mean that you cannot print the model in that material.
We did add some materials though: With the introduction of the new summer colors (basically painted WSF) we have made these colors available for all models that could be printed in WSF.
Would you mind giving an example of a model which now has 'wrong' restrictions? That would help in trying to see if there is some unintended behavior.
