Bug when loading frame sequence

Hello

Can anyone help? Any idea why it is doing this? Thanks 

The transparency options don't do anything, the only working transparency is alpha channel transparency in the pngs. So you probably need to check if the they are set up correctly.

Really? The color option wasnt supposed to take the color from the image and remove it, making it transparent? ??

No, you need to add transparency in the images. 

I think thats not right, volor option:

The function to use the color key has been removed a long time ago. Only some parts remain in the UI, I will remove them for the next update. If you want to use a color key you either need to use a shader or just export the files with alpha transparency.

Oh ok... thanks for the help, but i actually think it's something that helps, ill explain i created a video and turned into sprites, around 30 sprites, and clean each sprite from the background would be a pain, and was thinking in using the ingame color removal background, the color from the video i cant remove, because it removes unwanted areas, but whatever, thanks for the help.
