I have a 3D barn I modeled in the original 3d App (Cheetah3d) There is no problem in the render, When imported to Poser Game Dev 10.0.5 Mac as an object and rendered there is a white square in the roof. (on the side top.) What could be causing this?

Check if that is a polygon with a reversed normal.

Looks like a reversed polygon normal. Open the model, open the group editor, make a new fake group, add it and then click reverse normals & you should be all set. After that's done you can delete the group & export for Poser.

No it's not the normal I checked there is only one polygon and the normal is correct.

what happens if you zoom in on that white spot and render? What does the render look like? Get REAL close.

So that roof area/side is one large poly?

probably 8 polys for the whole roof would be my guess.

or 10

Nah, I meant just the area with the render anomaly. Just judging by his modeler image. It's moot though, he stated it's a single poly. Couldn't possibly be a normal issue... weird. 10 polys for the whole roof.

This has me Baffled

Humph. Probably pointless but set the materials to normals forward and render. Also, did you do any serious scaling to the object?

No scaling and normals forward in the materials made no change. Hummm.

Beyond my skills of Poser Prognostication uncle808us... if it's not related to the normals and you haven't flipped your object inside out (for lack of better description) from massive negative scaling, I too am stumped. Sorry.

Does the roof shake/shingle material use displacement? If so, what is your min displacement bound in the Firefly render settings? Show an advanced material room screen grab of the shake/shingle material, with all nodes fully opened (both the data section and the preview window).

I question whether the texture image is fitted to the UV mapping, given the black strip near the peak (one side only) and since the edge is above the roof when viewed from the back.

When remodeled with 2 shelled(thickened) separate planes for the roof. there is no problem...

No there is no displacement I have remodeled and the problem has gone. seachnasaigh posted at 5:41PM Mon, 22 February 2016 - #4256765
