WebCamTexture on iOS

Archived Forums Questions & Answers

I’m using a WebCamTexture on iOS to display a live background from the back facing camera. Unfortunately the image is displayed to dark. Adding Unlit shaders in the Editor works, but as soon as I use a shader on iOS the live preview is not anymore shown.

Can I increase the brightness of the WebCamTexture without using a shader? Or is there any shader that works with this texture on the iOS? Furthermore, is it normal to consume a lot of GPU/CPU so that my models rotate much slower in the foreground?

Thanks, Thomas

excellent question

You're forcing a root/hierarchical structure onto objects which affects what objects affect others when moved, deleted etc when all that is wanted is object filtering. It also adds more processor load too.

Ok, seems I found the solution myself (except for the poor performance). I needed to define a material with the shader and assign it to the texture. Seems using the default material and assigning a shader with renderer.material.shader = Shader.Find(“Mobile/Unlit”) does not work. The shaders are just not there on the device as no material is using them…

Have you checked out [NatCam][1]? It is extremely performant on both iOS and Android. Make sure you check it out. [1]: https://www.assetstore.unity3d.com/en/#!/content/52154
