Re: Speeding up the viewport preview

are we going to loose something by leaving this RT engine instead of adapt it to be decoupled ? isn't Rt more optimized for viewport render preview ? You loose the "zoom in" effect at the start of the rendering (i.e. rendering with large pixel blocks and than refine). P.S. I can decouple RT too but...

Re: Speeding up the viewport preview

I wonder if this is related to opencl and if cuda could speed this up. For example in octane there is a small delay between changes but UI is always as responsive as if no rendering is happening, so quick changes are no problem. In luxcore however we always have to wait for the update to register in...

On my system OpenCL runs about 9% faster than Cuda.
I don't know if this is a bad or a good thing :D But I'm expecting some proper perf. improvements once Dade starts adding cuda specific stuff.

Re: Enviroment Light Cache spots issue

Try using higher clamping values... These spots tend to show up mainly with low clamping. There are also cases where they show up no matter what (dense structures etc) and then there is no help.... But in your case it does look more like a clamping related issue Thanks again Laci, I think now I kno...

Re: BlendLuxCore Development

This is awesome, but for bump we still need to use "flat" mode + triplanar bump right? Yes, I was considering to add a bump mode as well, but I'm not sure how often bump imagemaps are even used nowadays. Do you use them often in your projects, or rather normalmaps? I almost never use normal maps. M...

Re: BlendLuxCore Development

I have added a projection mode setting to the imagemap node, there is "Flat" (uses UVs) and "Box" (uses triplanar mapping). Having this directly in the imagemap node means you don't have to use an extra triplanar node, which reduces clutter in node setups. I also did some general UI/tooltip polishi...

Re: Light passes

How fast it is when you use emission setting in volume node ? I don't know how would that work... But anyways, I'm not comparing speed, just saying that having exclusive lighting is a very nice feature to have... But, in general after few days of testing I'd say octane is about 3x faster on average...

Re: Light passes

I mean, we can do nice in luxcore too
cllux.jpg
but without dedicated lighting it's way more work and I personally wouldn't bother...

PS: this isn't speed comparison, octane was 30 seconds and it shows some ugly noise but it's for a small quick anim. I left luxcore render ~10 minutes.

Re: Light passes

here's an example of this feature, a still frame from anim. I'm doing in octane. 0026.jpg Now all this is doable in luxcore But. To achieve cloud like look of lighting I had to use 4 lights that are just affecting the VDB object itself. This in-camera compositing is a huge timesaver cause we can in ...
