How to render images? #3

Closed Wyverex42 closed 8 months ago

Wyverex42 commented 8 months ago

Hi,

thanks for this library, it works so much better than another library we were using beforehand!

I'm currently trying to render an image with ImGui. I found one example within the plugin itself where the font atlas is built and then the pointer to the UTexture2D is passed as an ImTextureID.

So I tried just passing a pointer to a UTexture2D (which is set as a default property on another class) to ImGui::Image but nothing is rendered. I also couldn't find where the conversion between ImTextureID and the actual draw commands is taking place so I can't say why it's not working.

Should this be supported?

Ah nvm, it works with other textures! There's something wrong with the particular texture I'm trying to use

Heya!

You should be able to just pass a UTexture2D pointer to ImGui::Image, for example:

ImGui::Image(GEngine->DefaultTexture, FVector2f(512, 512));
