Working with blurscreen

[Semajnad]

Hi All,

New to blur, and materials in general. Not sure what I've done wrong. What I'm getting is in the picture below ( any pointers would be great ):

	SB.VGUI.HeaderContainer.Paint = function()
		local blurTex = Material( "pp/blurscreen" )
		surface.SetMaterial( blurTex )	
		surface.SetDrawColor( 255, 255, 255, 255 )	
		blurTex:SetFloat( "$blur", 3 )
		render.UpdateScreenEffectTexture()
		surface.SetMaterial(blurTex)
		surface.DrawTexturedRect( 0, 0, SB.VGUI.HeaderContainer:GetWide(), SB.VGUI.HeaderContainer:GetTall() )
	end

I think you have to set the float up gradually or something like that ([URL="https://github.com/garrynewman/garrysmod/blob/master/garrysmod/lua/derma/derma_utils.lua#L30-L35"]since that's what gmod seems to do[/URL])

Also, you probably shouldn't be creating an IMaterial in a paint function

Sorry, it was outside the paint function, I just put it there to test something :P

And oh, I can try setting it gradually.

I've got it now thanks Whitestar - Neth helped out. I was just wondering why my blur was appearing as above, which I now have fixed. Thanks.
