Hi such great tutorials. I really need some help. I cannot get skylight HDRI to bake shadows, I’ve used your test scene mentioned in the above comments but the only way that my skylight will bake shadows is when Rtx is turned on. Yet your tutorial is not using rtx. I’m using HDRI backdrop set to stationary as per your scene. Really appreciate some help

[@theimageneers5161]

Hi Rich , The GPU Light bake tutorial is basically an HDRI assigned to the cube map ( Sky Light ) to spread the light by its colors and get the shadows , in your case it seems that something is not working as it should be if you have followed every step of this tutorial and your still facing the same problem please share your skylight setup and send it tour email [e-mail]

@@theimageneers5161 thanks so much for the reply, sorry I missed it. I think I found my issue was I was not using Lousuang GPU light mass. I switched to this and it worked as it should… I think. I’m still very confused between the deference’s in lighting between stationary and static lights when using HDRI skylight. Thanks again.

Thank you so much for this tutorial series. It really helps to get started with Unreal engine. If you don't mind I would like to ask you for your advice. You moved the hdri so it would not be visible inside the pool. What if instead of a pool you had an atrium that goes two basement levels down? How would you deal with this problem? In VR I would like to experience the hdri at groundlevel but unfortunately It intersects my atrium which goes down to basement level 3. Any advice would be highly appreciated. Thank you!!!!

Thank you , actually in 4.26 epic have made a tremendous upgrade where they have made the GPU light build is now an a ready feature and the results are way much better with the new options available but it will require raytrace to be on compared to 4.24 or 4.25 where you dont need to enable raytrace , our next course will include a detailed tutorial on how to use the GPU in 4.26 , hope that help answer ur question .

Is the Lighting Build quality affecting the GPU lightmass building time, or just the values of the variables in the ini file?

Thank you! I hope that this also help others

1) they do influence in case ur doing an interior scene 2) GPU will not be affected by world setting lightmass settings you will adjust them inside the ini file located in the setup location 3) Epic is trying to include the gpu build method in the engine but we dont know when they will release the version that include the gpu built in yet , no official news came from their side till now 4) to be honest this is one of the main issues that many are facing to do also , we will dig around and see if we can find a way around to do it . your most welcome

Is it still relevant now that we have raytracing

[@theimageneers5161]

Thats a good question , thats why you will also find more clear explanation on our Raytrace optimization tutorial where we used the light baked by gpu to compensate the Global illumination and increase the fps kzbin.info/www/bejne/m5bKmHiKf79jgKs

[@VitorCaldeira1980]

gpu is taking to long !!!! i set the sample count to 64 just like you. I have a pretty powerfull gpu

[@VitorCaldeira1980]

althoug the quality is awesome. what is the sample that i should use when i want to baket it for the final render?

[@theimageneers5161]

@@VitorCaldeira1980 Thanks for sharing your feedback , GPU is awesome on its soft shadow result you are right , to look for the best result for your final render this will depend on your scene if its simple and less detailed you can increase the sample count but if its a complicated scene i guess you gonna have to find an acceptable number to meet the accepted quality at an acceptable time
