Receive Shadow does not work

 

“Lit” on Billboard is turned on and the light that’s hitting the Billboard is a movable one in Unreal.

The Billboard is receiving the lights from the Unreal scene but not the shadows that the chair & floor are receiving. 

Anyone an idea why this is?

Hello, does anyone know how the Aximmetry support works? Will they reply here to questions or is there another place to get support?

If you look through the posts here you will see that they answer questions, but it will often take a few days (at least).

Hi Johan, thanks for your reply. 🙏 You are definitely the best Aximmetry Support. You are everywhere all the time with so much knowledge. It seems like Aximmetry outsourced this job to you ;)

I noticed that they respond as well, but was wondering if they respond to every case or if they have a support email that I haven’t found yet.

Anyways regarding my issue here. I worked on it the last 3 days and it seems that Aximmetry has issues with this hard/detailed shadows. In Unreal it works great. So if you have an idea what I can check, I’m happy to hear that. Other than that have a great day!

Thanks! Regarding support you have the option of a paid support plan for faster response times. This forum is basically all the support that is included in the base price, as far as I know.


Does the real-time shadows work on translucent materials in UE4? Translucency is handled differently in many ways in UE4, so shadows might be one of them.

Hi,

Currently, Aximmetry's talent billboard can not receive shadows, as the material used by the billboard is a translucent type.
Note, that since the billboard is a 2D surface, such shadows can look unrealistic. As the shadow projected on your billboard won't bend on your talent's real-world geometric features.


However, you can try using Surface Forwardshading translucency lighting mode, which can show directional light shadows, but has its own problems and is resource-heavy.
For Surface Forwardshading, open the Billboard_Lit material in the Aximmetry Camera's folder.

Set Lighting Mode to Surface Forwardshading.

On your Directional Light, set its mobility to Movable.

And increase the Num Dynamic Shadow Cascades of the Directional light to 4-5 for less pixelated shadow. (for value 5, you need to type in 5)

Surface Forwardshading will only make shadows from Directional light work somewhat well. Other light sources will probably cause bad pixelated shadows or poping in shadows on the billboard. Also, lights will act differently on your billboard.

Otherwise, it might be possible to make your own complex materials/shader that can receive shadows.

Warmest regards,
