Hi!
I think that you can do the inverse, instead of starting to do your edits in SOP and then start working in LOPs, start working in LOPs by loading your USD (with a sublayer or reference node) and make the edits inside of a SOP modify LOP.
If you want to continue starting in SOPs, you can export your edits, and then in LOPs load the original asset and then load your edits layer, it will override without changing the rest of the data (the materials and assignments) if you don't change your path and usd attributes of course.
I hope this helps,
Cheers!

Hi!
Maybe you can take a look at this Component Builder video:
https://www.youtube.com/watch?v=EgTqz6y_oAs&t=2s [www.youtube.com]
I think if you are not looking to automate the re-process of the asset you can use the component builder by manually re-building each variant with each proxy separately, and then merge all the variants.
You can find the modified hip attached.
I hope it works for you,
Cheers.

Something happens with your attached hip file that crashes my Houdini after few seconds 
But I would say that you should not use the Houdini Render View when you use Redshift, maybe you have a incorrect gamma applied there. You should use the RS Render View.
Maybe you just need to tweak some extra values in Redshift to close the look that you got in Mantra.
If you think that you need more help related with redshift, you can try to post it on redshift forum on the Houdini section:
https://redshift.maxon.net/category/26/bugs-houdini [redshift.maxon.net]

Yes, you can define the default values for the HDA parameters, or you can also use the Create Python section to run a script once the HDA is created, in case you want to save only one HDA but create it in multiple ways with different initial values depending on how are you calling, you can create a shelf script to create your HDA and control the initial values with it.
Regarding the pre-defined list, you can create an Ordered Menu parameter instead of a string field like in the example.

Hi!
I'm not sure if I'm following you right but, maybe the Folder as "Multiparm Block (List)" can do what you are looking for?

Hi! Did you checked that the Redshift License is correctly assigned on the Maxon App? And also check if you have the latest version of the Maxon App.
Just to make sure, you can also check that your machine has the license assigned on:

Hi!
I don't know if this can help you entirely, but I have a Mtlx sRGB -> ACES CG hda that you might use as starting point, of course as the name say, it will only convert the sRGB data into ACES CG space, but in theory you don't need the 'raw' conversion because that one is the same as linear and the you can use the same node to convert HDR data:
https://github.com/dynestudio/DyLib/tree/dev [github.com]
Hope that helps, cheers!

Hello!
I want to ask if someone knows which is the process to add a Schema to one primitive using Python and the PXR module? I'm trying to do a "translator" of USD lights from C4D to Houdini and I want to try to assign the "ShapingAPI" schema to the Spot Light to have the correct viewport guide representation:
I saw that this is how it looks on the usd file:
Also it would be interesting to apply the "CollectionAPI:lightLink" schema to translate the light linking data too, but let's see if the ShapingAPI can be done first :P
Thanks a lot!

Hi!
You should try to post this on Redshift Forum: Solaris / Hydra section:
https://redshift.maxon.net/category/38/bugs-solaris-hydra [redshift.maxon.net]
It will be better if you can attach a basic repro .hip file to help juanjo to see what's happening more quickly.
Cheers!

HI, does Houdini 19.5.493 supports all Redshift versions upon 3.5.12 or it just works with the 3.5.12, installing the plugin from the link that @CYTE attached (?)
Hi! In theory Houdini 19.5.493 supports from Redshift 3.5.13 to Redshift 3.5.14
You can check the supported versions of each build here:
https://help.maxon.net/r3d/houdini/en-us/index.html#html/Houdini+Plugin+Configuration.html#Plugin [help.maxon.net]
There is indeed a RS 3.5.12 custom build on the RS Houdini Custom Builds thread, so in theory that one should work for H19.5.493 too.

Hello!
I want to ask what are the steps to bake textures with Karma? I saw on the Karma vs Mantra [www.sidefx.com] page that there is a preliminary support on H19.5 Karma CPU for this:
But the only element that appears on the TAB menu for bake is not related to this:
Thanks!

Hello!
Could you try to post this on the Redshift Forum? I Don't think that the RS dev will check the reports here.
https://redshift.maxon.net/category/38/bugs-solaris-hydra [redshift.maxon.net]
I'm wondering if this problem can be related to this thread also:
https://redshift.maxon.net/topic/46764/lag-opening-a-file-maybe-related-to-rs/8 [redshift.maxon.net]
You might try to rename the cpu dll too.
Cheers!

Houdini is almost frozen when I enable the Camera handle (cingle viewport), and the focus handle, making very difficult to use it to define the focal distance from cameras, and is added because it doesn't happen all the time, probably ~95% and with simple scenes.
Thanks!
Yes, I have issues with the camera handle too. I press the keyboard shortcut to make the focus handle appear.... and nothing happens. Thought I was going insane. I've only just started testing out Houdini Apprentice to consider purchasing Indie but the amount of bugs I have experienced just performing very basic functions has put me off for now. Maybe v20 will be better?
You don't need to use Solaris to learn Houdini at all
.. Actually, maybe when you are learning Houdini I'm not sure if it is a good idea to learn Solaris too instead of the common OBJ context/workflow, you can still evaluate Houdini and if it fits your needs the Indie license will be worth it
