Not on GPU, since it (still) doesn't support sphere primitives...

But using a master object and having your other points made out of instances should work on GPU too.
Either way, your IGS can become very big, since each object gets quite some info about material, position etc.

Hey polygonmode, in my understanding of IES it is a purly 2 dimensional information that get extruded like in a Lathe Nurbs. Therefore there shouldn't be any "other side of the light... I attached my way to work with IES (and light in general): via material Emitter and a mesh you put it on. Your way...

Hey polygonmode, nice to see you giving Indigo another try after all these years, welcome back! For IES lights try using only a single 1 triangle emitter, since each triangle of the emitting mesh starts emitting its own IES... Maybe just share your C4D scene and IES file so I can have a better look ...

Hey Pavoda, this is really well done stuff, the light feels very nice an welcoming with some love to detail. Only the last image shows that Indigo needs some kind off falloff Material for Peachfur (couch). The blue chair could also need some more attention :) But really a nice Project and awesome re...

You should try harder mate:
Again:

A) Set Material to single Sided Arch Glass

B) You have some massive absorbtion on your Glass that turns it opaque, turn off the absorption

Hey Alcaide, please make sure to use "Single Sided Arch Glass" for your Window glass as long as it has no thickness and is made out of a simple plane. You uploaded only the igs, make sure to save out a pigs that packs all meshes and textures into the file :) If you have issues always double-check to...

it will be valid for all v4 releases (4.5, 4.5, 4.x)

Hey Yader,

thanks a lot for your testscene!

Tested and reproduced your issue. Talked to the devs and it seems this is a "known limitation" that for GPU rendering 32bit emitters (all but EnvMap) get converted to 8bit at the moment, will be fixed in the future...

best to upload the pigs, so the devs have a testscene

a great example for the terminator artifact issue.
Please have a ultra high subdivided sphere, instead of this "low poly" one and also give the CPU more time, that should "fix" this issue.

what Indigo version do you use?
Try the latest: 4.4.1

Disable the CPU

Hey Sroka8888, just as Ono explained the denoiser is only working with GPU rendering atm, and you are right: its because of the sampling method CPU rendering uses. Saving EXR does work fine, but does take quite some time since on saving the denoiser restarts. If you also save Render Channels it does...

Hey rivera-b,

try disable your HD Graphics 4000 for GPU rendering!!
Its usually only causing issues due to driver support of OpenCL and in older working Indigo versions it slowed down the render for sure, go back and test it.
