Question about motion blur.

[juangea]

Currently a lot of things are being improved in LuxCore.

I’m always amazed by the development pace you guys have, it’s not because it’s fast or slow, it’s because it’s steady, like a bulldozer going forward over features, it’s amazing to be an spectator of LuxCore growth

With that said, I wonder if deformation motion (or full motion blur) blur is on the roadmap, it’s one of the few things that we miss in LuxCore, to blur water (super important to believable water sims rendering) , particles (not sure about this one, because it may be just transformation motion blur and in that case this is already implemented, right?) or characters (also a basic need for characters), and even OpenVDB volumes.

Is it planned?

I know LuxCore is not aware of time, but with the evolution we are having, could be good to make LuxCore time aware in general or at least for the most important things, like proper full motion blur

Thanks for everything, I’ll do an English live streaming about 2.4 once it’s released, I already did one in Spanish, but I have the English one, the most important, in the to-do list

Embree can support mesh motion blur for CPU and now Optix can support mesh motion blur for GPU (assuming the results are compatibles for CPU+GPU rendering).
So it is now possible and relatively easy because it is delegated to external libraries.

What happens with CUDA and OpenCL?

Would that mean a difference in feature set?

Yes, in this case, OpenCL would not have support for mesh motion blur.

Given AMD has started to drop OpenCL support in their libraries, they may drop driver support too, first or later: OpenCL is plain dead.

And what about CUDA?

And what about CUDA?

Do you mean CUDA without Optix ? It should affect only some very old card: Optix supports all NVIDIA GPUs of Compute Capability 5.0 (Maxwell, i.e. many years old GPUs) or higher.

[juangea]

Ah, ok, so you enable Optix no matter if it’s an RTX card or not

Good to know

Thanks.

Hi guys!

Testing BlendLuxCore an I like what I'm getting.
Now I'm testing a scene of syrup pouring into glass with cocktail and ice.
Liquids are pre-meshed in RealFlow alembic mesh cache and imported as mesh sequence into Blender.

I'm having trouble of getting no deformation motion blur on imported alembic mesh with velocity data (from RealFlow).
I'm relatively new to Blender and LuxCore and maybe here is a bit dumb question. But is there any option to have the velocity extracted from alembic file and used to get proper deformation motion blur?

Thanks in advance!

I hope that deformation motion blur will be supported in 2.10 version.

At the moment only solid object movements have motion blur but deformation based motion blur - i can not get it work so i guess it's missing at the moment.

It would be great to have motion blur for alembic files with velocity information and of course directly inside blender (cloth, softbodies, skeletons/rigged characters and shape keys.)
