it turned out. I have a lot of new discoveries and questions. I made a general group of three cone beams with jars. Saved in OBJ. I assigned all the cones in the MTL file d 0.01, this is the minimum possible. Almost nothing. I returned it back as a model. It's very interesting that it's not the first time I've seen models that are complex in shape come back into the program in slightly different proportions! I don't know what to do with it. After all, 8 powerful spheres of 100% each sit inside the new cans, if they pop out even a little bit because of the new dimensions of the group, there will be trouble))). It's okay, I put them carefully back again. The new picture was loading... drum roll ...)) the same 5 hours. Oh no. I was so hoping for Captaincook's advice.. But it looks like transparent JPG models and opaque PNG models are equally difficult for the processor. It's a pity, the Nobel Prize is postponed. The new rays turned out to be gentle. I'm going to use this method of super-transparent models in interior renderings to demonstrate furniture when it prevents you from seeing more important details. This is the next topic.
