Question

I’ve made a syringe model and made a screen for it


But in game the display doesn’t show me image

and outputs me these errors:

either you have to use a sprite3d with a viewporttexture or you have to use a subviewportcontainer. the first one should be better for your problem

[mkmysterykey]

I can’t use sprite3d bc im using spatial shader for pixelisation and sprite3d doesn’t render. This shader is the best I found so I don’t want change it

[mkmysterykey]

btw I read the documentation and I did everything right I guess

Using a SubViewport as a texture

[herrspaten]

So your meshinstace3d has the subviewport texture as material override?

[mkmysterykey]

yes it is

[mkmysterykey]

ok i think it is an engine bug
