Blender to Aximmetry - problems with shadows

 

Dear Aximmetry-friends,

I´m totally new in working with Aximmetry and want to create a setup that we can use in our greenscreen studio. First: I love Aximmetry and all the posibilities you have. The problem is:

I have created a "curved wall" in Blender and have it exported to Aximmetry. There I will put a video on it to play in loop as a background. Everything works fine as long as I not throw shadows on it. When the shadow gets to heavy, in the "curved section" of the wall all lines appear, that should not be visible (see screenshots).

I´m sure, that I´m doing something wrong in Blender, because when I use a cylinder created in Aximmetry the same shadow looks absolutely nice.

Thanks a lot for all your answers, Holger

Hi Holger,

First off, welcome to the world of Aximmetry! It's great to hear about your enthusiasm for the software and all the creative possibilities it offers.

It seems you might not have enabled smooth shading in Blender for your object. To do so, simply right-click on the object in Blender and select either Shade Smooth or Shade Auto Smooth:

After applying the smooth shading, you can expect the appearance of your curved virtual screen wall in Aximmetry to change from this:

Into this:

I hope this resolves the shadow issue on your curved wall. Best of luck with your creative endeavors in Aximmetry!

Warmest regards,

Thanks a lot for your help!

Unfortunately it doesn´t make any difference when playing around with smoothing. The good thing is, that the effect only appears when I put the light or the shadow to extremes (like in your first picture). But I´m not able to reproduce your second picture.

I hope, that I´ve eveything configured right in the flow-window:

Hi Holger,

Thank you for your update. There is indeed some artifact with the shadows when using the Spotlight module with high Falloff Angle values.

One potential solution is to disable receiving shadows for the curved wall. Since you probably intend to create an emissive virtual screen, such a screen wouldn't typically have noticeable shadows in a real-world scenario. You can disable the Receive Shadows in the shader of the model:

Alternatively, you might opt for the Spot Light GW module over the standard Spot Light module. The GW version can accommodate higher Falloff Angle values without generating the shadow artifact.

Please explore these suggestions and let us know how they work out for you.

Warmest regards,
