Is there a limit on the texture resolution in Prospect ?
I created a poly mesh from 3D scans and photos, then decimated to a reasonable poly count, from original 99 million poly's down to 1 million, while maintaining a high resolution texture.
I sent the file to Prospect VR directly from Rhino.
The textured mesh looks great in Rhino:
but looks terrible low resolution in ProspectVR:
I was wondering the same thing. I subscribed a few months ago to do a walk-through of one of our designs and had used a photogrammetry software to recreate the google earth topography of the site. In sketch-up/blender the texture looked nice and crisp but once in VR the resolution was dramatically decreased. Is there a way to manually override the texture size limit somehow?
Hi Chase and Pat - thanks for flagging this. Prospect runs texture compression on large textures from your models, and since most photogrammetry contains very large textures, the compression is much more visible in those files. I've logged this in our system, and we'll plan to roll in a feature in the future that will allow you to adjust texture compression when needed.
Hi Nathan and Tim - as you have noticed with Prospect, we clamp textures at 1024x1024 total pixels to help with file optimization, though there is no limit on the overall number of textures. This resolution limit helps optimize the experience to run in our engine at top frame rates.
As a short-term fix, I spoke to our team about this and it sounds like some photogrammetry software suites allow you to export tiled images instead of one massive texture. If that's possible on your end, a good workflow you might try is dividing the size of your tiles by 16 - this should help improve the fidelity of the textures.
Longer-term, we plan to support larger textures and we'll keep you updated. Thanks for the feedback!
