Fixed output texture sizes?

Hi - we’re seeing consecutive frames generated with different texture sizes. The frames are being produced from a CLI script and although our Unwrap setting is 8192 we randomly get some with 8192 PNG texture and some with 4096, even through adjacent frames are practically identical models. I realise RC is being smart and optimising, but is there any way to force a fixed output size? It’s not in any way critical (we can upscale of course) but am curious if there’s a way to force RC’s hand?

Hi, 

what are some typical utilasition values for some of the 4k and 8k textures?

Looking at two adjacent frames, one with a 4096 texture and one with 8192, the 4096 has 91% and the 8192 has 80%. Another of the 4096 ones has a 92% usage. Maybe the pretty random distribution suggests I’m coincidentally close to some decision threshold and the choice can go either way?

Hi, 

Thanks for the update, I was actually expecting a lot less utilization on the 8k textures. Please can you screenshot your unwrap settings?

edit: or the xml for the unwrap

Shout if this isn’t what you need:

Hi,

please can you show me the texturing for a 4k textured model, and also for an 8k textured model?

Here’s a 4096:

 

…and an 8192:

Hope it helps!

Hi, 

please contact support@capturingreality.com, and if you can a dataset for the 4k one and the 8k. I have a plan for a method to force 8k, but i don’t want you to do the trial and error for me, in case I have to try a few things that don’t work.

Hi Wallace - thanks for sticking with this. Have sent a mail to Support referencing this conversation with a link to the RC projects and image data (note the XMP’s we’re using to stabilise the actor just in case they have some bearing on the issue).

Hi,

In case anyone is following this thread the solution was to unwrap with fixed texel size set to .009. This meant the texture would no longer fit onto a 4k map
