Best way to get good texture
« on: January 13, 2018, 06:17:23 PM »
I would like to know the best way to to get the best texture.
I would like to create good model to put on sketchfab to show to my customer.
I use the Sony A7RII but drone and ground.

i guess we chooce High for built align, dense, mesh
But then built texture, what is the best way?
I don't know what is 4096?
Can i put 100 000?

It is possible to get the same quality on orignial photo and on the final model 3D mesh texture?

4096 in square is the pixel size of the texture picture that wraps on the mesh.

How large you can make a texture file ist depending on your video card and size of the video RAM.

A GTX1080ti with 11GB Video RAM is able to process a 32768x32768 pixel (1Giga pixel) texture file.
A GTX 960 with 4GB Video RAM ist able to process a 16384x16384 pixel (192Mega pixel) texture file.

But you can split the texture file in more pieces with the texture making process. It is better for uploading to 3D model libraries and visualisation on slower PC.

For Sketchfab it is better do to maximum 8192x8192 Pixel (67Megapixel)
The maximum supported file size per texture is 75MB. However, we recommend staying well below this limit whenever possible. Such large images use a lot of resources, and are usually overkill. Keep in mind that we will not render textures larger than 8192px × 8192px

It is depending how you process the model with Photoscan. With a lot time you can process you model in very high Quality and it is look like a photo in 3D....but you need really a lot of time...

You can use Tiled Model generation to get the texture resolution close to the source data. However, it cannot be uploaded to Sketchfab, but there are some other online platforms that allow direct tiled model upload from PhotoScan.

Which online platform are you thinking? You mean that it isn't maybe necessary to use sketchfab but there are others better way?
I am not know what is tiled model generation, I will look on YouTube to find it. Do you have a link to see what is it?

For sketchfab, for upload we fisrt start to upload the .obj then the texture in setting? Cause usually I upload 3 folders together but the max is 200 MO.
