render.RenderView doesn't work on cam.Start3D2D

[Yuri6037]

Hello all,

I hope someone will be able to answer me. So I made a cam.Start3D2D to create a screen on a security cam screen model.

The cam.Start3D2D pos/angles/scale is ok. But render.RenderView won't render in this cam.Start3D2D it alway renders in my HUD with removing my first person models !

Here is my code :

//Function called like ENT:Draw()
function ENT:CustomDraw()
	local ent = Entity(self:GetNWInt("BoundCam"))	
	local pos = self:LocalToWorld(Vector(6.6, -5.4, 4.9))
	local ang = self:GetAngles()
	
	ang:RotateAroundAxis(ang:Forward(), 90)
	ang:RotateAroundAxis(ang:Right(), 270)
	
	cam.Start3D2D(pos, ang, 0.1)
		if (IsValid(ent)) then
			local CamData = {}
			CamData.angles = ent:GetAngles()
			CamData.origin = ent:GetPos()
			CamData.x = 0
			CamData.y = 0
			CamData.w = 90
			CamData.h = 90
			
			render.RenderView(CamData)
		else
			draw.RoundedBox(8, 0, 0, 90, 90, Color(255, 255, 255))
		end
	cam.End3D2D()
end

Nobody ? So nobody has used the RenderView before me ?

[Yuri6037]

Anyone ? I really need that for my gamemode...

[Yuri6037]

Still nobody ?!

Why are you ignoring my post ! I saw another post which is the same problem !! And you have never solved the problem.

So I re ask you again : Why do you just ignore this topic ?????!!!!!

Because, We don't know the solution, not everyone can solve all problems here. TIP: Research and test.

[Yuri6037]

I already searched and even tested but all I can get is render.RenderView function ignored, hl2.exe has stopped working, all view models deleted, and render.RenderView not changing anything with game laggy at 5 FPS !!!!

[Yuri6037]

I managed to make part of this function working however it's TERRIBLY laggy !!

Normaly I have arround 90~100 FPS. Using render.RenderView working version it drops directly to 60~50 FPS. Spawn 3 of these entities and enjoy your 20~30 FPS !!!

Players are however invisible, only the Physgun glowing effect is visible on the cam.

Here is the new code I managed to get :

function ENT:Initialize()
	self.Texture = GetRenderTarget("realistic_cam_" .. self:EntIndex(), 128, 128, false)
	self.Mat = CreateMaterial("realistic_cam_mat_" .. self:EntIndex(), "UnlitGeneric", {["$basetexture"] = self.Texture:GetName()})
end

hook.Add("HUDPaint", "RenderViewTest", function()
	for k, v in pairs(ents.FindByClass("realistic_camera_screen")) do
		if (v:GetPos():Distance(LocalPlayer():GetPos()) > 100) then continue end
		local ent = Entity(v:GetNWInt("BoundCam"))
		if (IsValid(ent)) then
			local cur = render.GetRenderTarget()
		
			local CamData = {}
			CamData.angles = ent:GetAngles()
			CamData.origin = ent:LocalToWorld(Vector(10, 0, 0))
			CamData.x = 0
			CamData.y = 0
			CamData.w = 128
			CamData.h = 128
		
			render.SetRenderTarget(v.Texture)
				render.RenderView(CamData)
			render.SetRenderTarget(cur)		
		end
	end
end)

function ENT:CustomDraw()
	local ent = Entity(self:GetNWInt("BoundCam"))
	local pos = self:LocalToWorld(Vector(6.6, -5.4, 4.9))
	local ang = self:GetAngles()
	
	ang:RotateAroundAxis(ang:Forward(), 90)
	ang:RotateAroundAxis(ang:Right(), 270)
			
	cam.Start3D2D(pos, ang, 0.1)
		if (IsValid(ent)) then
			draw.RoundedBox(8, 0, 0, 90, 90, Color(255, 255, 255))
			surface.SetMaterial(self.Mat)
			surface.DrawTexturedRect(0, 0, 90, 90)
			draw.DrawText("Cam #" .. ent:EntIndex(), "DermaDefault", 90, 80, Color(0, 0, 0), TEXT_ALIGN_RIGHT)			
		else
			draw.RoundedBox(8, 0, 0, 90, 90, Color(255, 255, 255))
		end
	cam.End3D2D()
end

Well it is rendering everything again so what do you expect?

I don't know but on the CAP (CarterAddonPack), this was eating really no fps... You know the kino screen, it does not eat any fps...
I tried to see their codes, but I can't find where they're rendering the kino screens...

As far as I know they aren't rendering that themselves, they're just using default rendertarget texture for screen and [IMG]http://wiki.garrysmod.com/favicon.ico[/IMG] [URL="http://wiki.garrysmod.com/page/Global/UpdateRenderTarget"]Global.UpdateRenderTarget[/URL].

I just saw that. I advanced a bit with render.RenderView. I found a way to icrease a bit my FPS, instead of unplayable it's playable but still laggy.
Indead, as strange as it seams, increasing texture size from 128x128 to 512x512 and by capturing on GM:PostRender, it brings me 5~10 FPS, which makes the game playable.

However, now instead of not rendering player models it renders them but screwed up and in my HUD not in the rendertarget texture...

[Yuri6037]

So after some more tests, it seams that the player model screwed up problem is only appearing when you're watching yourself through a screen...
