Rive error

Bugs
#1

I would like to use Rive in my game. I just added the rive extension dependency, but the game now crashes with the following error:

[mvk-error] VK_ERROR_INITIALIZATION_FAILED: Render pipeline compile failed (Error code 2):
Link failed: The type of fragment input user(locn2) does not match the type of the corresponding vertex shader output.
ERROR:GRAPHICS: Vulkan Error (…/src/vulkan/graphics_vulkan.cpp:1615) VK_ERROR_INITIALIZATION_FAILED
Assertion failed: (0), function GetOrCreatePipeline, file graphics_vulkan.cpp, line 1615.

I am using a Mac, with Defold 1.9.6 and https://github.com/defold/extension-rive/archive/main.zip. I have also set OpenGL Version Hint to “Highest version available”.

Any help?

Did you also set the Rive renderer in the game.project > bootstrap > render?

#3

No, I just added the Rive extension. I have no Rive contents, just my game as before.

Also, the Rive defold sample project works fine.

You have issues with your shaders, they are not compatible with metal/vulkan. The error says that the input and output doesn’t match. So check that your varyings are correct

I forced the use of Vulkan with an appmanifest and I get the same error without the Rive extension. I will try and find these mismatches in my shaders and report them here.

I am now able to run the game with Vulkan BUT:

  1. There was no mismatch in my shaders. I have just reordered the varyings in each .vp and .fp pair so that they are defined in the same order. (!)

  2. My models are not showing anymore in the game… Note that some of them were already not showing in the editor.

What should I do?

#7

Can you share the project or the shaders with me? I have no idea why it wouldn’t work

@jhonny.goransson Many many thanks!

I will prepare a minimal project with only a shader and a model and send it to you.
