Hi everyone. I am just trying to export several vertex vec3 attributes and render them in 3ds Max. So far I can only render 1 attribute, Cd, but I fail with others.
Can someone explain the workflow to me?
How can I render my custom attributes?
Thanks in advance

MartybNzWhen Mantra is such an awesome renderer, it is not right to wait some 3rd party rendering softwares to solve just a few minuses. And by solving them they are bringing even more.
What are you looking for in particular then? Arnold and the upcoming Octane surely cover all the bases no
Mantra is one of the best renderers in my humble opinion.
I do remember that in Houdini 14 wishlist there was a discussion about implementing proper indirect illumination solutions that are fast and flicker-free. Bruteforcing is not an option when in comes to indoors. There are alot of speed comparsions and tests that some of the users did. Dont get me wrong please. I am really glad about the new features, but it seems like Devs are just ignoring that fact, that GI in mantra is a little bit bad when it comes to more that 1-2 bounces of a ray. Octane is handicapped just because it's GPU-based. It is very fast and cool, but you cannot render complex stuff with colored millions of particles with smoke and so on.
When i saw a sneak peek of Hou 14 features i was hoping that second video will popup with some rendertime improvements atleast. It was obvious to me that Devs are actually listening to users and doing some stuff from their requirements or suggestions. For the past year there was a lot of discussions about Mantrs's speed when in comes to GI. Fur rendering got improved, but its more like of a trying to fix lost leg with a patch. Sorry for my english

MartybNzSadly i did notqbick
And nothing about rendering speed improvements and global illumination. One of the worst releases.
Perhaps you missed the section ‘LIGHTING AND RENDERING’

Hi everyone. I'm former Softimage user and everything related to VOP's is more native for me, so I've tried to replicate attribute wrangle code in attribute VOP. The problem is - it is just not working as it should. I've attached an example file. Inside of a DOP network there is SOP solver connected to constraint relationship network. Can someone dive inside and check mine attribVOP please? There is also working attrib wrangle connected which is working perfectly fine so you would see what effect I'm trying to replicate.
Basically if attribute called angle is greater than some value - primitive must be removed. Attrib wrangle does the job, but not the attrib VOP.

ive got 16 gb's of RAM and not even 1 gb is used when rendering this scene.
in error logs its asking to check if there any pcclose or something like that.
can it go for infinite loop or something?
i dont really know anything about that kind of stuff.

i just simply want to combine volume light with gilight for nice light scattering result.
result, as expected, is really nice, but there is some kind of error in houdini debugging console:
i can only move my lagging mouse pointer - nothing works.

also you can watch what kind of effect im talking about - http://clip2net.com/s/5gEG1Y [clip2net.com]
this is only test result, but i cannot continue my tests just because of too frequent crashes.

I'm happy to report that with latest beta drivers ver.320 there is no freezes anymore.

MurciallogoI wish that it would never happen.
I wish Sidefx could buy or cooperate with Cebas, and integrate THINKING PARTICLE in Houdini 13. Node based architecture of thinking particle will perfectly fit into Houdini, and will bring Houdini's particle system to a new level

loccitanehuge performance loss on H11 viewportfgillis
I have the same problem with the GL 1.2 2.1 & 3.2 viewports. Am still using an older 12.1 release so it may have been fixed since.
To get accurate point and primitive numbers, (and to see duplicate point or prim numbers), I always switch back to the “H11” viewport. Click on Edit/Preferences/3D Viewports, then select “H11” as your “Scene Renderer”.
cool, that fix the problem. I switched to H11. Btw, what will i loose when switch to H11 ? i mean what significant feature that will be lost ? So far the interactivity in modeling seems to be nice.

lets say i have shattered sphere and instead of simulating RBD sim i want to modify each shattered piece's position, scale and rotation as particle.
how can i do that?

johnnycoreSame thing - freezes on 314.
I just tried out the latest driver to see if things are improving: GeForce 314.07 Driver
But nope.. now it even freezes at the splash screen!
Isn't there anything we can do about this as a community?
It keeps getting worse with every release, so maybe we should spam nvidia..
