Active Radius parameter for a Dome Light March 4, 2025, 4:58 p.m.
I've been looking into this also honestly, as I need to light something that is within a sphere, and wanted to invert the dome light to emit light from the middle as opposed to outside in. Adjusting that oddly worked but not 100%, it's -1 by default, and going to .01 allowed things within the dome to accept the envlighting. I don't think it's accurate though.
Packed Disc Sequence, setprim Intrinsic farm issues Feb. 2, 2024, 8:11 a.m.
So I have a solution from Matt at Sidefx, i'll be testing it soon. The condensed notes is that in Solaris, the SOP Import does not see packed prim sequences correctly, when setting 'Packed Primitives' on it to "Create Point Instancer", the index jumps around frame to frame because the prototypes are changing per time / frame. You have to do a couple things to get this to work right. First in OBJ / SOP level you must add a prim wrangle after you do your timeoffset / setptrimintrinsic wrangle. In the wrangle after that you must set the path per object via 's@path = sprint("object_name_%04d", @primnum ), hence generating a path PER object. Once back in Solaris, on the SopImport node, set it to "Native Instances" and things are once again stable.
Packed Disc Sequence, setprim Intrinsic farm issues Jan. 28, 2024, 5:40 p.m.
Hi all,
I've been doing a setup for myself utilizing animated geo as packed disk sequences to utilize the index attrib on them, based off the helloluxx training and others . When rendering local via Solaris / Karma I have zero problem, things push thru just fine. However when sending this super simple setup to a farm via a USD Husk submitter, my sequence is just all broke. It appears as if random frames are just pulling from within the usd file. I've pulled the usd file that Houdini creates into a viewer and its all "glitchy" there also. Upon further inspection I've grabbed the locally created usd submission file via the standard Karma render ROP, thinking that since that renders fine locally it should be ok. Nope, same issues. I've tried adding a cache in Solaris in various places, after the sop import, end of chain before the render settings node to no luck. Any advice as to what is going on potentially? It seems like its def time based, like something is not reading the exported usd properly.
Thank you in advance
Tim
