## Most critical reviews (4 lowest-rated)

### 1/5 — Can't see the render

*2023-09-16*

The only way to see the object is to turn on the wire frame. I wish I could have learned this without spending the $10. Useless!

### 1/5 — Seems like Apple code

*2021-01-07*

This app really feels like it’s a sample code to open 3D files in SceneKit, the price is really really high for that

### 1/5 — Does not open my .scn file

*2020-11-21*

App does not seem to open my .scn file. 
Cant find any method to submit support request on support page.

### 3/5 — how do i add shader

*2025-09-22*

where can i add shaders im on iphone tho is that it

**Developer response:** Hi,

This app only allows to open and show existing files, including SceneKit files that contain shaders. In other words, you need to create the shaders in Xcode and store them in the SceneKit (.scn) files.

Hope that helps!
