Question by Dark-Protocol · Sep 18, 2014 at 07:40 PM · cameratexturecoroutinetexture2drender

Render a list of objects into a Texture2D array

I have an array of game prefabs and I want to make thumbnails of them (in runtime) like in the editor. I have a coroutine that is supposed to take care of t$$anonymous$$ngs. However I can't seem to render the objects properly, all of the thumbnails appear empty (just the camera background).

T$$anonymous$$s is the code: IEnumerator RTRoutine(){ if(previewCamera != null) Destroy (previewCamera); Camera cam; previewCamera = new GameObject("_AssetCamera"); previewCamera.transform.position = -Vector3.forward*10f; cam = previewCamera.AddComponent (); cam.depth = 100; cam.cullingMask = (1 << 19); cam.clearFlags = CameraClearFlags.Depth; cam.enabled = false; for(int i = 0; i < gamePrefabs.Length; i ++){ GameObject previewObj = (GameObject)Instantiate (gamePrefabs[i], Vector3.zero, Quaternion.identity); yield return new WaitForSeconds(0.1f); yield return new WaitForEndOfFrame(); previewObj.layer = 19; cam.targetTexture = assetPreviewTexture; cam.Render(); RenderTexture.active = assetPreviewTexture; assetPreviews[i] = new Texture2D(64, 64, TextureFormat.RGB24, false); assetPreviews[i].ReadPixels(new Rect(0, 0, RenderTexture.active.width, RenderTexture.active.height), 0, 0); assetPreviews[i].Apply(); Destroy (previewObj); } Destroy (previewCamera); previewCamera = null; }

Why are the thumbnails appearing empty ? I can see in the editor that assetPreviewTexture updates with all of the objects ontop of each other (yeah, it's like they just stack up and don't destroy).alt text
