This texture map was created with the CT8 Pipeline demo. I have not tested if it will create a higher resolution UV map texture if you start with an obscenely high resolution image, but I wouldn't count on it. I have not found a setting for it yet either. This is geared for real-time performance after all.

While it is true for real-time performance, this is only relevant for preview mode, and there is already a way to reduce texture size for preview. There is no reason to skimp on texture size for final rendering. I was kind of disappointed when I saw the CC texture map because there is a lot of wasted space that could have been used for facial details. Within CC you're using Substance which gives very nice results indeed. This you throw a way when using the face fitter, at least I believe so.

I'm a newbie so I may be the only other person experiencing this problem, but you are not alone. The face imported into CC does not come close to the detail created in CT 8. Resemblance is marginal at best.  I tried the proposed fixes posted on this forum with no real improvement.  Anyone think a fix is in the works?  Or possible?

Well, I wouldn't say it is marginal, but I do notice a loss in detail and I think it's something to do with the downsampled resolution.  The exported maps ARE the right size (they are the normal "largest size" available, which is 2K) but they appear to be missing some detail which I put down to a resample somewhere.

If that's all it is, then a fix would be easy for RL.  We'll just have to wait and see what they say about it (although it's unlikely that Peter would know, and Eric won't comment).

It just donned on me as I was walking to the grocery store that the reason the head ends up being at about the half the expected resolution, is because it is at half the resolution. When the UV texture map is generated, the head is just a portion of it. as well as being the entire head. So, the original face image, even at 4096, is only going to be about 1024-ish, with a similar amount for the rest of the head and ears. The lips get a significant portion of the image as well.

This texture map was created with the CT8 Pipeline demo. I have not tested if it will create a higher resolution UV map texture if you start with an obscenely high resolution image, but I wouldn't count on it. I have not found a setting for it yet either. This is geared for real-time performance after all.

It sure looks like a huge amount of space is dedicated to (wasted on) the top and back of the head.  I'd rather see many more pixels applied to the main facial areas - nose, eyelids, eyebrows... sort of like what was done for the lips.

Has anyone found a fix for the resolution issue? I am using a very large image texture like 8k when making the head in CT8 and would really like to keep it at at least 4k when importing into CC3.   I think the "Realistic Human head Packs"  are created with Crazy talk 8 right?? They have large texture size so it must be possible.

Unfortunately, 2048 x 2048 is the maximum texture size you can export from CrazyTalk 8.

When you export an RLHead to CC you will only get 1k textures by default. 

However, in CT8 you can select Create > Texture Settings from the Menu Bar and save the head and body textures. These will be 2048 x 2048. You can then manually apply them in CC.
