Render camera to texture no longer working?

[quid21]

In P3D V5.4 backwards, I could render a camera to texture eg. for mirrors.

In P3D V6.1, this no longer works. The render to texture for my P3D default ground radar works, but the render to texture for my cameras do not.

As far as I can see, this feature hasn't changed in the SDK, so I believe it to be a bug.

In the cfg I have:

[CameraDefinition.5]
Title = "narrow"
Guid = {20751A39-E38A-4BE7-B35A-7BD79B85D356}
Origin = Virtual Cockpit
Category = Outside
MomentumEffect = FALSE
SnapPbhAdjust = None
SnapPbhReturn = FALSE
PanPbhAdjust = None
PanPbhReturn = FALSE
Track = None
ShowAxis = No
AllowZoom = false
InitialZoom=0.0
SmoothZoomTime = 0.0
ZoomPanScalar = 0.0
ShowWeather = Yes
XyzAdjust = FALSE
ShowLensFlare = TRUE
PitchPanRate = 0
HeadingPanRate = 0
PanAcceleratorTime = 0
ClipMode = Normal
HideShadows = 1
HideReflection = 1
HideModels = 1
HideParticles = 1
HideUserAircraft = 1
HideAutogen = 1
HideScreenSpace = 1
HideMissionObjects = 0
ShowLabels = FALSE
HideSky = 0
HideTerrain = 0
RenderToTexture = TRUE
RenderToScreen = FALSE
UseGlobalTerrainView = true
OffsetP = 0
OffsetB = 0
OffsetH = 0
InitialXyz = 0, 10, 0
InitialPbh = 90, 0, 0
AllowBelowGround = false
TextureSizeX = 1024
TextureSizeY = 1024
VerticalFOV = 56
HorizontalFOV = 56

In the gauge I have:

<Gauge Name="narrow" Version="1.0">
<Image Name="background.bmp" />
<Element>
<Position X="0" Y="0" />
<Texture Name="narrow" Width="100" Height="100" />
</Element>
</Gauge>

Hello,

Thanks for the report. Are you able to see the RTT view if the panel is undocked? Also in the camera configuration file the minimum supported zoom value is 0.3.

Hi Rob,

This camera is set up so that it is applied to a texture map in the virtual cockpit, I don't use a camera configuration file - only the cfg posted in above that is in the aircraft.cfg the title, in this case 'narrow' is directly referenced in the gauge xml.

I will try changing the zoom value, however, to achieve a downwards looking viewsight, I used the field of view values directly from the pilots manual. I have a separate part called 'wide' for the larger field of view. I'll report back if adjusting the zoom to 0.3 changes anything.

It used to work in previous versions of P3D until V6.1.

Thanks for looking into it.

EDIT: Adjusted the Initial zoom value to 0.4, but no difference. Its odd because the RTT for radar still works, just not the camera....

It looks like the alpha channel of the RTT view is 0 for some reason. We'll try to track down why and fix it but you could work around this by using TEXTURES_USE_ADDITIVE_BLEND=1 in your panel and making sure you have a black/dark background under the texture.

Code: Select all

background_color        = 1, 1, 1
TEXTURES_USE_ADDITIVE_BLEND = 1

When docked the texture draw uses an alpha blending material mode to allow it to blend with the windows behind it.

Hi Beau,

Thanks for your kind reply.

I tried your suggestion and it produces some results, although in the case of things like mirrors and in my case downward looking optical viewsight, I can't really put a dark background since the view is an outside view facing down, so no blending required - but happy to await a fix.

We found the underlying issue. This will be fixed in the next patch. Enabling sharpening for FSR2 is a workaround you could try in the meantime. The post process shaders for those write 1 into the alpha.

If you're texturing your windows with a vcockpit $ texture rather than the RTT texture directly, you could set an darjk background in the panel as i described. You could also add disable_alpha_write=1 to your panel if you want to make sure the final $texture ends up with 1 for the alpha.

If you are texturing directly into the model, you could also change your material blend state to make the mirror opaque which will ignore the diffuse/albedo alpha.

Will take a look at those options.

Many thanks Beau.
