I have rendered a 400 frame 360 degree stereoscopic medical animation that consists of a boxfull of mParticles. (See attachment)
Particles represent 3 particles in the blood. (Neutrophyl, Macrophage and Natural Killer Cell) My camera is in the middle of the box, surrounded with a collision sphere so that particles don't come very close to the camera. Scene is rendered perfectly.
I need to add the names of these three different particles on one of each type over the rendered frames.
As the viewport is not capable of correctly previewing 360 degree projection, it is very hard to place the text in the correct position.
I noticed -however- that Interactive render somehow moves the particles to the correct position in the viewport. (Just as in the rendered image) I determined the particles which I'll link the texts to, displayed their particle IDs and linked the texts to three particles by using Script Controller.
When the Interactive render window is active, (After moving the time slider one time) I see the texts perfectly aligned throughout the entire animation. Texts move with their corresponding particles. They are in the middle of the rendered image as they should be.
If I start production render the texts move to the lower left corners of the stereo pairs, totally incorrect place.
Only moving the time slider in IR mode updates the text positions to the correct place. (See the attachment with region render)
I'm literally out of ideas. What might it be, that updates the text and particles during interactive rendering, but not in the final rendering?
Edit: I ve attached the 2020 version Max file file for those who are interested in. It is originally created with Max 2020. (Saved from Max 2021 though) Didn't include the maps as they are only background files. I tried to convert it to the oldest version possible to make the file available to more folks around here, but the particle positions change completely when converted to version 2018, so the oldest version I could save was 2020.
