Re: problem with using a Mops instances
In your example file, the problem is that in the Unpack SOP you're transferring "UV" from the packed geometry to the unpacked geometry, which mangles your original UVs. Just leave the UVs as vertex attributes before the Instancer, then when you're done with the MOPs stuff, unpack using the default o...

Re: problem with using a Mops instances
Packed geometry in MOPs is no different from packed geometry anywhere else in Houdini. If your objects have vertex UVs prior to being packed (or input into the Instancer), those UVs remain embedded in the geometry. They will not be directly accessible to you without unpacking, but the render engine ...

Re: FBX displays material in viewport but not in render
Ah, perfect! Yeah this is a bit of a flaw in the packed primitive workflow... if it isn't obvious to Mantra where your material definitions are, it'll just skip them unless you embed everything. You can also dodge this problem a little more efficiently by using stylesheets to assign materials, but y...

Re: FBX displays material in viewport but not in render
Try this... on your Mantra ROP there should be an option called "Declare Materials". Set that to declare all materials in your IFD. It's possible Mantra just can't figure out what materials should be included in the IFD because of the way they're applied. Let me know if that changes anything.

Re: FBX displays material in viewport but not in render
I haven't worked much with Megascans assets so I'd just need to know a few more details about how you're handling the instancing. How are you importing the FBX data? Are you importing the file to /obj first and then merging it into SOPs, or are you doing it some other way? Where is the material assi...

Re: MOPs to Point Instances shelf tool
Okay, just reviewed it again in your scene. It seems like it's working as expected. You want to be at the OBJ level when you activate the tool. Hit the shelf button, select the object network that contains the MOPs packed primitives that you want to convert to point instances, then hit Enter. You sh...

Re: MOPs to Point Instances shelf tool
Seems like something's not working quite right here... I'm taking a look at it now.

Re: Houdini Indie Steam install
I haven't run Houdini Indie via Steam before, so I'm not sure exactly where it assumes the preferences directory is supposed to be. It may be different with the Steam install than the usual /documents/houdini18.x directory that's used for a typical installation. To find out where Houdini on Steam is...

Re: mistake during transaction along line
Hi Andre, The issue here is that you are computing an orientation on the curve (via either the built-in orient options on MOPs Move Along Spline, or the MOPs Orient Curve SOP), but the curve is changing every frame! The transform option on the Labs Spiral is actually deforming the curve, and so the ...
