Houdini: 'Fixing' Megascans Displacement Issue w/Redshift

dude wtf. every video i find to help with this ads more confusion and headache. starting to loathe plugins inside houdini. my megascans plugin box does not look like yours as it doesnt have the CONVERT checkbox like yours does. smh.

Is an HDA for this process still in the works?

Hey great video, im running into a issue where when I go to select my high LOD in the file node. Instead of seeing all the LODS separate LOD 1 LOD2 LOD 3, etc. I see only one option that is "LOD$F". Your help would be greatly appreciated

Mmm... It is a grey=zero displacement map, pixel values of 0=displace inward, pixel values 127 (mid grey)=no displacement and pixel values of 255=displacement outwards.
Just offset the color on your texture in the shader and everything should sit in place correctly.

I’m a bit a noob but is it possible to bake my own map using substance with their textures?

Thanks you for this tip. Its one of the problem inside houdini even if you are using mantra.

Very insightful and helpful, I too bumped into this problem recently having just started with megascans so thank you for sharing your findings. Have you found a way to convert the displacement map from log to linear inside Houdini COPs context?

Thanks for the video, very helpful. Does anyone know how to go about the log to ln conversion without Nuke?

This is so helpful.
Thank you!!

Hi thank you so much for this video!
I was wondering myself why the LOD0 asset looked worse than a basic mesh with a mountain node hahah...
I also thought it had to be the colorspace, glad you confirmed my suspicion, and thanks for all the information you have pursued in this issue.
Please keep my posted if you bump into anymore amazing knowledge, subscribed! :)

Damn, I just managed to take a look at the thread you posted. I always assumed the discrepancies were due to their intention of not being the same. I don't wanna do the same thing I have to do when importing my scanned objects!

tHIS A great Tut, but this defeats the idea of megascan, and they should fix it....
maybe this could be automated in some way?

Hey, while in my opinion even the highest poly LOD is prety low poly and I like the idea of creating a lod from high poly sources, are you sure there wasn't something wrong here? LODs from megascans look quite good when setup correctly.

thanks! again, really helpful!
I have a question. in Renderman the default displacement 0 is 0.5.
the range is -1 to 1
you mentioned black would normally be 0.
is that an absolute / universal truth, or something that might change for any render engine's own standards?
is a negative displacement not wanted /not something that's usually done?
could you make a guess as to if 0.5 is referring to 50% brightness or a spacial dimension? and if should remap it?
no worries, if you're wrong that's no biggie.
