renderdoc | RenderDoc is a stand-alone graphics debugging tool | Graphics library

I have a strange issue, a vulkan application I am writing seemingly runs fine when run from the terminal. But if run from renderdoc an assertion inside the official .hpp header triggers.

Since this only happens if the program is launched with renderdoc I am having a hard time trying to debug it.

Is there a way to get the exact environment configuration renderdoc is using to run the program so that I can replicate the bug?

It is quite bizarre it only happens if the new dynamic rendering extension is active too. If it is not requested renderdoc doesn;t seem to trigger the assertion. But I am on the latest version (1.18).

I'm trying to apply a custom effect using the DirectXTK. The effect is supposed to be an "unlit" shader with just one texture. But for some reason, the texture is stretched across the model. I looked in renderdoc and the texturecoordinates appear to be loaded correctly so i'm not sure what's going on.

Environment of work: Unity3D 2021.2.7.f1 Direct3D11

I try to make Laplacian Smoothing working on GPU For this case I set up Compute Shader among others VertexBuffer(input Graphics Buffer) and outVertexBuffer( output Grpahics Buffer), unfortunatelly I have a weird problem with storing data into GraphicsBuffer (storing vertices Vector3) which i use as "output" of compute shader.

Assigning of ComputeShader component:

In 7.5, the Vulkan spec says about vkCmdWaitEvents

The first synchronization scope only includes event signal operations that operate on members of pEvents, and the operations that happened-before the event signal operations. Event signal operations performed by vkCmdSetEvent that occur earlier in submission order are included in the first synchronization scope, if the logically latest pipeline stage in their stageMask parameter is logically earlier than or equal to the logically latest pipeline stage in srcStageMask.

I'm confused by this phrasing. Does this mean the first synchronization scope is the signalling of events that are passed in to pEvents, plus any events that are submitted earlier and meet the stage mask and submission order requirement, or is it event signals are both passed in and meet the requirement?

In either case, since you can just pass in events with pEvents, what is srcStageMask is useful for?

I am trying to update the value of a uniform variable within my shader using an ImGui slider however the value I pass in is correct on the CPU side but when its at the GPU it becomes a negative value. I give an example of how I am setting this all up where someVal is the value being passed to the GPU which represents the radius value in the image I show (Naming was changed to help make things slightly clearer). This is what I am currently doing

I'm a new android application engineer. I'm trying to make a vulkan rendering backend demo which use SurfaceView as a View on android Java code. I made the gles rendering backend demo using GLSurfaceView as well. On application code, I use setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) API set activity from default portrait to landscape. But it doesn't work on SurfaceView while it works on GLSurfaceView.

I use renderdoc capture the rendering result, the image is in landscape layout(the same layout as gles backend). I doubt it was's something wrong with some settings on activity or window, but can't figure it out the root cause. Could somebody help what maybe the problem is?

Here is the Java source code.

I encounter an issue when I transmit uniform buffer data from CPU to GPU side. It seems something to do with memory alignment between CPU/GPU. I define a uniform buffer object as follows:

I'm trying to implement model loading, but I'm stuck with one problem. When i try to draw a mesh (a single textured quad written by hand for test purposes) for some reason duplicated data associated with the first vertex is passed to the vertex shader (RenderDoc screen).

Here is an example using a stripped down version of my class that still exhibits this behaviour:

library:assimp;model:*.fbx

the skeletal animation can be played normally. But the character’s neck is stretched and does not move.

use renderdoc to find that the vertices of the input vertex shader are no problem. But the output vertex shows that the neck is abnormal. i still can't tell where the problem is

the character’s head can’t move and the neck is stretched. i want to know where exactly is wrong? What goes wrong can make the head unable to move?

this is the result when the error occurred:

pass the input to the shader
