Maybe you can use the detachable joint? I.e. add a fixed joint that you detatch when you need to adjust the angle?

Why do you want it to be a revolute joint, and not a fixed joint? Is it because you want to simulate sometimes with the

Hi,

I'm trying to control transparency (of parts of a mesh) with a fragment shader.

As a first test, I tried to adapt the deformable sphere example by changing the alpha value in deform_fs.glsl:

i.e. change

fragColor = vec4(finalColor, 1);

into

fragColor = vec4(finalColor, 0.5);

But it remains opaque.

Defining another visual in the sdf without shaders but with element <transparency>0.5</transparency> does yield a transparent object. Adding the <transparency> element to the visual with the shaders has no effect.

Is there a way to do this in the fragment shader?

The answer is here

Hello,

I've seen the ROSCon presentation (video - slides) on "How to Achieve Realistic Visuals in Ignition Gazebo", and this community meeting recording on the same topic.

Both give a nice overview of the possibilities, but don't really discuss the "how" to do this, other than mentioning Zbrush, Substance painter, 3ds max and blender.

In the ROSCon video also a "custom 3ds max script" is mentioned to export to sdf, but i found no further references to that script.

I found this plugin to export Albedo/Roughness/Emission/etc from Blender, and I succeeded in generating some png's, but I can't get them to show from the sdf.

Would there be any more info on how to do this?

The ShaderParam plugin can be used to define shader parameters in the sdf file. However, except for the 'time' variable, these are all constant values.

What is the preferred way to set such variables during runtime?

E.g. for the deformable sphere example: let's say we want to change color of the sphere at runtime, based on user input. How could this be done?

Is there a way to do this on a per-model basis? E.g. if you'd spawn multiple of those spheres, change the color of a specific one.

The answer is here.

There is also an example world wide_angle_camera.sdf.
