What is your specular depth?

Hi Karba,

Octane has a serious issue or limitation!
Can't render a scene with many different ies. I think that Octane can't handle too many photometric datas.

I created a scene with about 20 different ies photometric lights and instanced them. In the scene I have about 500 or more lights.

Unfortunately I can't render all of them because some photometric light distributions disappear and they are rendered as spherical lights.

I think you can explain this issue. Gpu limitation?

regards
(I'm using the 1.18 because is faster and the latest release does't convert all textures, ies, hdrs, etc.)

Please check the texture statistic. Every ies texture takes one gray scale 16bit texture.

specular depth is 8,glossydepth is 4, aodist 4 and diffusedepth 4

Try to increase glossy depth to 8 or more

hi
i setup this version of plugin but i have any more crash
my system is : 8 g ram M.B intel dp45sg and i have 2 gpu a:msi 580 oc b:pny 580

Hi Karba,
are you joking????

Can I use only 10 photometric is files with my Titans????

With iray I can use any number of ies photometric I want.

Please find a solution for this issue. Thank you.

Did you check the texture statistic? What does it show?

Hey Karba, could you please share some info on how to change to different kernels via maxscript, like those "actionMan.executeAction" values - I just want to switch from say PT kernel to Info kernel, and render material ID - and want to make a button of it, cause I'm doing this now a lot,

- I'd just like to implement those kernel buttons into a script for faster switching, when you make a scene, and change textures, this is mostly what I'm doing anyway, switching textures, cameras and kernels for different versions
