No, it’s a sequence with “name 001.png” … . Should the .ifl help? The simple named sequence is working for rectangular lights.
…
I tried the .ifl file method now and it’s not working in GPU mode, only CPU mode.
So, we found that ifl or sequence are working in CPU mode, but only particular in GPU mode. I hope it can be fixed on the plugin side and no core fix is needed. What do you think?
