I have a material which with time starts to selfilluminate more and more. When I render frame 1 (no self illumination) and then frame 10 (high self illumination) the change is visible. But if I render range from frame 1 to frame 10 - no self illumination appears. I believe it is because arnold somehow cashes materials and textures for animation. How can I make it work? Thank you.

What's self illumination?
Emission parameter of a Standard Surface shader?
yep emission ( self illumination was in mental ray 🙂 ) but I do use Physical Material and as I said if I go to frame 10 and render it alone it will be illuminated. But if I render whole animation the emission setting will stay at zero as it is set for frame one.
I don't repro that in 3ds Max 2019 with Maxtoa 2.3.34
"I don't repro" means "I tried it and I did not reproduce the problem"
Check your Arnold logs for warnings
Yeah i tried to repro that too in a smaller scene where only sphere with illumination texute was used. It worked. I dunno why but in the other scene where it doesn't work corectly also bump maps do not work. It is large scene of a detailed spaceship. No error logs though. It just doesn't work. Probably some kind of arnold bug, cause the bump map problems in larger scenes were discussed in many topics.
Did you try use "Re-translate Scene on a Frame Change"?

p.s. MAXtoA possible have problem with transfer complex scenes. In my case problem when rendering hair. Hair and Fur, it's works well in small scenes but with complex some times hair disappear. Render again and it's works. Again ... disappear..
thank you the retranslate option was what I was looking for. Anyway Arnold does have many problems in complex scenes... I have experienced Hair and Fur problems myself 😞 hope they will fix it soon.
