main menu with a 3d model

Post by hrohibil »

Hello

Sorry if this is probraly a basic unity question.

I am using the Menu frame work extras and i try to add a 3D model to be part of the menu, but what ever i do it is not visible in the camera / game view?

Hi,

Screen Space - Overlay canvases always draw on top of everything else. Here are 3 different suggestions:

1. Add a second camera that looks only at the 3D model. Configure it to render to a render texture asset. Then add a UI Raw Image to our canvas, and assign the render texture asset.

2. Or use 2 canvases:
  • Use the first canvas for the title menu. Leave it set to Screen Space - Overlay.
  • Move the background image(s) to a new, second canvas. Set it to Screen Space - Camera. Then you can set its Plane Distance, which is the distance from the camera.
  • Add your 3D model at a closer distance to the camera.
3. Or change the entire menu system canvas to Screen Space - Camera. This will require some adjustment to make everything look the way you want.

I want to go with option 1 but it seems i am missing something.

this is my steps:

1: I create a new camera
2:I set culling mask to ONLY my model.
3:I create a Render texture
4: Add the render texture to my new camera
5: Add a Raw Image to the canvas.
6:Add the Render texture to the raw image.

Issue now is that the whole screen fills with this new render texture??

Make sure to set the size of your Raw Image UI element.

You may also want to set the render texture camera's Clear Flags to Depth Only.

Did the depth part.
How do I change the size of raw image? Scale does not work?

No change.

Change its Rect Transform like any other UI element. It works the same as a UI Image except it shows a texture instead of a sprite.

YES YES it worked.

Is the raw image, can it handle 3d movement? Cause when i play my player object has animation, but for every movement he generates large trails?

IS it only meant for static iamge?

Hmm, you may need to put a background behind the character and set the Clear Flags to Solid Color.
