Transition between two textures in a filter: second texture gets scaled

[jawaka 1]

Hello.

I'm trying to make a filter to transition between the current texture of a Sprite and a new one.

I've put together a barebones example here: https://www.pixiplayground.com/#/edit/KozVneSNjCuVZKi_fgNJa

When you click on the blue sprite, a filter is applied. Currently, this filter takes a new texture as uniform and uses it to sample the fragment color (I have removed all the blending code to make it clearer). And it seems as this texture is being upscaled?

Both textures have the same size. As a reference, I have added a second sprite with the new texture being applied.

 

Thanx in advance!!!

Nevermind.

I forgot to normalize the coordinates of the texture sent as uniform (vTextureCoord * inputPixel.xy / outputFrame.zw).

Everything is peachy now
