CG trader purchase texture issue

[native-education]

Hi there, I purchased a model off CG trader .cd4 version R17 Render: Octane4 and am having a lot of trouble getting the materials/textures to come in. The first time I opened the model, the material was there but looked locked and the model was all grey. I saw one of your other threads that said go to the takes tab, but I couldn't see that this was locked. I then copied/pasted the materials into a new scene. This worked, but the materials weren't linked to the assets when I put them back into the scene with the model.
The second time I opened the model, the materials all went a bright white. Now it keeps doing this, and I can't do anything. I have tried to relink the materials via the project asset inspector, but this is not working either. It only looks as if half the materials are here, too, which is strange. I desperately need your help as I need furniture to upload into my architecture models, and this purchase cost me $100NZ - I will need to do this regularly, so I need to get this right. I would be happy to send you the zip file of the purchased model if this helps.

Thanks!!

Hi native-education,

Please note that I do not have an Octane Render license, which means I do not support this render engine.

Have you set the path in the Preferences to your folder with the textures?

Paying for images, some tips:
I assume you have a good source for images, so place them into a folder to access those for each new project instead of saving them during the work. (Archiving them should be done with save with Assets.) Good textures-sellers tell you on their website at which light temperature they were shot or corrected to a specific one.
Also, they should be in Adobe RGB or a larger color space. The tiny space sRGB can't even reproduce all reflective surface colors (Points's Gamut), and only a third of the visible frequencies, AKA: colors. Converting an sRGB to a larger space doesn't bring clipped colors back.
If you spend money, find the best source. R17, as an age reference, should be checked carefully.
I have my fair share in architecture, to know that colors are a critical point. If you use HDRI, avoid ".hdr" formats at all costs (typically no color management and no information on what was used, but some save it as EXR, which doesn't improve anything.) Some offer even white-balanced HDRI images, missing the whole point while explaining it with even weirder ideas, which is sadly done to some of our Asset Browser material as well, to make the swappable while removing all the correct colors. Be picky, to keep it short.

All the best
