CustomerDear Soft8Soft Enterprise Support Team
At present, the display effect of the same export file on the PC and the mobile phone is completely different, and the display effect of Android and Apple mobile phones is very different. We ran on an Android device and reported such a prompt. We believe that this error is the reason that Android and Apple devices display differently.
Please help check and analyze, thank you!2020-04-10 at 9:10 am #25617

FunJoy.TechCustomerHi, Yuri. dndc001 comes from Dongfeng Nissan group. They have tried it on 3.0.1 version, encountered loading issues on computers with Intel HD 520 & 620 graphic card. But apps made in 2.16 version can run on these devices.

1. On the same computer, the program developed in version 2.16 can be opened, but it cannot be opened in version 3.0.1. This question has been sent back to your company and team by email;
2. For the same exported file, the display effects on the PC and the mobile phone are different, such as the screenshot of the problem feedback;
3. The same exported files, Android system and Apple system, have different display effects;
Thank you for your help to solve the above problems. Thank you very much!2020-04-10 at 11:52 am #25624
Alexander KovelenovStaffHi @dndc001,
1. On the same computer, the program developed in version 2.16 can be opened, but it cannot be opened in version 3.0.1. This question has been sent back to your company and team by email;
The HD 520 device should arrive by the end of the next week, we’ll try to reproduce this issue and find a proper fix.
2. For the same exported file, the display effects on the PC and the mobile phone are different, such as the screenshot of the problem feedback;
There is a known issue on some Android models which have linear texture filtering feature blacklisted. It can affect HDR-based environment lighting but not that much. Can you send us your HDR map to the Enterprise support email so we can investigate this issue further?
I also found that you have the so-called z-fighting issue on your model. You can eliminate it by reducing camera distance stride (increase Clip Start value and decrease Clip End value as much as possible). Also, try to place your surfaces not so close to each other. For example if you have multi-layered geometry try to place layers so that they have some minor distance between them.
2020-04-14 at 1:50 am #25724CustomerThank you very much! We will sort out the relevant information as soon as possible and send it to you by email! Hope to help reply after receiving! Thanks!
2020-04-14 at 2:34 am #25725CustomerSorry, due to the company’s email policy interception, we will first send you the HDR image used in the exported file and screenshots of related issues, please check! Thank you!

Apple devices support only WebGL 1.0 as such they can’t handle non-power-of-two textures well. Your HDR map has 1292×634 size but we recommend using 1024×512 or 2048×1024 size instead. This will resolve the issue with the image being too bright.
The Android issue with darker image is indeed connected to blacklisted float texture support on some devices (in most cases they have Mali GPUs). This feature is required to handle environments which have wide dynamic range of intensities. We will continue to try figuring out possible workarounds for this hardware defect though.
P.S. Intel GPU hardware is on the way, we will get back to you as soon as we receive the delivery.
