Question by cineboxandrew · Apr 21, 2017 at 02:05 AM · camerarendertexturecubemap

Rendertexture release error

I'm getting a runtime error on startup of my game

the error message:

 Releasing render texture whose render buffer is set as Camera's target buffer with Camera.SetTargetBuffers!

the source code that produces it (commenting it out results in no error message):

 using UnityEngine;
 
 public class SkyCamera : MonoBehaviour {
 
     public Cubemap cubemap;
 
     // Use this for initialization
     void Start () {
         GetComponent<Camera>().RenderToCubemap(cubemap, 63);
         gameObject.SetActive(false);
     }
 }

Is there something I need to do to release this properly? I'm trying to render a bunch of procedurally generated geometry to a skybox cube map so it doesn't have to be rendered each frame (it has a lot of small sub-pixel triangles and transparency layers). the cubemap variable is set in the editor to the skybox material's main texture, and it work fine, besides the runtime error.

After the first line in the Start void, try adding the following;

 GetComponent<Camera>().targetTexture = null;

I'd assume that in disabling the camera, it releases all attached render textures first. But seeing as that texture is the target for the camera it might be causing conflicts.
