-AttachRenderdoc gives more (useful!) Information in Unreal Insights but I don’t understand why

[simonschreibt-code]

I noticed something weird (but useful) in UE5.5.4:

When I start my game with enabled Renderdoc-Plugin and -AttachRenderdoc I get MORE INFORMATION in my Unreal Insights Trace.
I placed some cubes with MI_simon material and as you can see, they do not appear in my trace when Renderdoc is not attached but are shown when Renderdoc is attached. VERY USEFUL to know what actors are actually rendered.
I thought, maybe more trace channels are “secretly” added by Renderdoc, but this is NOT the case as you can see by the trace.statusoutput.

❓ Does anyone have an idea, why Renderdoc “gifts” us with useful information while NO trace channel (i tested enabling ALL) nor -statnamedevents / Stat NamedEvents 1 is a able to do the same? ❓

Repro is easy:

new project + enable renderdoc plugin
add boxes in simple level and assign material/instance
add -AttachRenderdoc to your “Additional Launch Parameters” in “Play in Standalone Game”-Settings
trace with unreal insights
in the timers-tab, search for your materia

Solution (thx goes out to tzupi!):

You can make these material events appear with r.ShowMaterialDrawEvents 1 ! Then -AttachRenderdoc is not necessary anymore.

In the picture you can see how the events appear as soon as I endered the command.
