Summary

Good morning,

I updated my map (2944-7170-7283) for Halloween.

The modifications were accepted and published, however, I wanted to change the thumbnail of the map, but it seems that the upload did not work.

I specify that this is the image in 1920x1080 px.
The 1024x1024px image has been successfully uploaded

I respected the formats and type imposed in the file selector.

If anyone can help me please

Hey StereoChips,

It should be working if you select the private version of the published map, and publish it again, replacing only the thumbnail and stating what has changed which is only replacing the thumbnail.

hi @StereoChips , @Hardcawcanary ,

The reason is that as of 31.20 the Power of 2 was enforced in the Validation of assets.
The new function “Conform Texture” was made to allow assets of 1920 x 1080 to change is NOT Power of 2

My post on this is quite extensive but there is now a Power2.PDF file with all the Powers of 2, which Conform Texture creates.
The values 1024 x 1024 conform to the power of 2 are correct.

The uploading function does not have a way of informing you just silently enforces Power of 2 on everything.
Conform to Texture has fixed many problems with Project Memory size for my projects

In another post “How to test for the Power of 2 on Calculator” was written
How to test for the power of 2 textures

This was difficult for many to understand so the Power of 2 table was created

the candidates for power of two are
2 to power 43 1849
2 to power 44 1936

2 to power 33 1089
2 to power 32 1024

leaving 1849 x 1089 , but of course there will be distortion so you need to load this into Windows Paint and crop to size to avoid distortion
