Im building an old building thats long gone and only image I have is an old photograph, issue is that I cannnot really use it as a backdrop in left, right, top views etc when its shot at an angle (like most buildings) is there any way I can get an image into backdrop in perspective view in modeler?
thanks in advance

im not 100% sure, but if you add it to layout backdrop and align some geometry there, I think the backdrop comes across with the "layout View" in modeller, was only added recently though so if your on older lightwave its not there, you can then tweak the view in layout and resend it as you build,

you could use a dome with a mapped background, but it is risky.
You could go to environment tab ..add textured environment, and set up your backdrop image there, though this is mostly prefered with cylindrical or spherical maps.

I would suggest, select your camera, and use match camera perspective in the viewport drop down list..so you have the same angle and perspective when you switch to camera, you may need to set camera focal to 33mm to match that of perspective.

in order to continue to orbit in a similar way as with perspective view, you should add a null and camera target it, make sure the null is at your desired target point.

But there

Surely its not too big a deal to allow a backdrop image in perspective view!? Ill just have to give up on the dream of having a backdrop image in perspective as I couldnt get any of those options working. Thanks anyway guys...

Not sure why you would give up?...textured environment should work for you, what happens if you use textured environment?
Or do you mean specificly OpenGL aware, cause you need VPR active for textured environment to show up

You are trying to model the building? Any way you can get old floor plans for it? You also might be able to use Photoshop (or some other paint program with similar features) to straighten out the angled building using its deform/transform tools. Of, course, you would have to mentally interpret some of the structures, but it would serve to.

As far as seeing a backdrop in VPR or texure Pesrspective mode, make a rectangular polygon, and map the image to it's surface. This can be seen readily in Layout.

I used that trick back before Layout view in Modeler was a thing. (https://www.gian-cursio.net/wp-content/uploads/2013/05/Junk2.jpg) I just constantly tabbed back and forth from Modeler to Layout to check my alignment. It wasn't ideal, but it got the job done. My understanding was the entire purpose of Layout View in Modeler was for exactly that, though I haven't tried it out yet.

yes it is, you just set a single view, set the camera to the same pixel as image, set backdrop in the backdrop options, no need to add an image world or anything, then also use the match perspective tool.

Blah...I was talkin with my nighthat on obviously, missed completely that it was about modeler..Not Layout (shame)
