Especially with semi-transparent meshes, the render order plays a crucial role. Now it can happen that everything is correct in the content tool, but the order in the simulation is wrong.
When exporting, the Content tool combines identical materials and meshes that have completely identical properties (i.e. material, animation, visibility, etc.). This often leads to a change in order, but since the Content Tool always shows the unmerged version, everything looks normal there.
A mesh property is planned that it may not be combined with others. As long as this is not the case, the mesh can be "separated" by having other properties:
- Other visibility (variables, flags...)
- Other Animation
- Other material, whereby it must be noted that the material is really "different", i.e. at least one parameter is set slightly differently. That should be enough!
