Any way to disable mouse cursor bloom/light effect?

mateusz.grabowski · December 19, 2021, 11:33am

Is there a way to disable this feature? I looked into settings file but didnt find anything. I am not really fond of it.

If you can compile Rack on you own, you can disable the mouse cursor bloom/light effect.

In file RackWidget.cpp search for //Draw mouse spotlight and comment out the code below.

Thanks for the reply. Unfortunately I don’t know how to do that. I made a request to the support maybe it will be added to the view tab. It’s not that big of a deal honestly

Where can I find the file? I would like to try.

follow the instructions on VCV Manual - Building to download the Rack source and all dependencies, then compile the whole thing and check if it works, then search for the file you wish to change (mostly in a subdirectory of Rack/src) and apply your changes.

          		float t[6];
          		nvgCurrentTransform(args.vg, t);

          		nvgFill(args.vg);
          	}
          
          
	// Draw lights and halos
          	Widget::drawLayer(args, 1);

Also, be aware, that if you’re on windows, you need special make dep to get ASIO if you build Rack yourself

RTAUDIO_ASIO=1 make dep

@Ahornberg @Jens.Peter.Nielsen

I was joking. I thought it was something simpler like changing the settings.json

If I try, I may be able to not get lost in code, but I prefer to use time differently these days.

mce076 · December 19, 2021, 1:45pm

it eventually will be… i raised a feature request to have a control (slider) added to the view menu to adjust brightness from off to full spotlight that was accepted

Ahornberg · December 19, 2021, 1:49pm

sorry, I took you seriously

zwayne · December 19, 2021, 1:51pm

Excellent! I was going to send this suggestion on and am glad you already did it. I find the light bloom quite annoying when I want to record a patch (with video of course)

Dr4am · December 19, 2021, 2:11pm

I was serious. Before I realized how complicated it was. Here in Italy when you want to do something and then you realize that maybe you are not capable, it is customary to say “I was joking”

shofb · December 19, 2021, 6:49pm

Setting the bloom to0 turns it off.

carbon14 · December 19, 2021, 6:53pm

It controls the bloom from lights, but not the mouse spotlight, which I think is what the OP is asking about.

Jens.Peter.Nielsen · December 19, 2021, 8:11pm

Jens.Peter.Nielsen:

		float brightness = 0.2f;
		// Draw mouse spotlight
          	//	nvgBeginPath(args.vg);
          	//	nvgRect(args.vg, 0.0, 0.0, VEC_ARGS(box.size));
          	//	nvgFillPaint(args.vg, nvgRadialGradient(args.vg, VEC_ARGS(internal->mousePos), 0.0, radius, nvgRGBAf(0, 0, 0, 1.f - b - brightness), nvgRGBAf(0, 0, 0, 1.f - b)));
          	//	nvgFill(args.vg);

I commented those lines out, and the “room brighness” in the menu only controlled the cable brightness. The room had constant high brightness.

changing float brightness = 0.2f; to float brightness = 0.f; worked - no more light around the mouse pointer.
