A few issues relating to 3D model slipped through the net and were affecting the r506 release, so we're releasing a hotfix to correct those. This also fixes the new Arcane Express example project failing to open.

In case you missed them, the release video has been included again above, and see the r506 release notes here, which includes 3D lighting, 3D model animation blending, and more.

  • Like someone posted previous post, there's a weird problem with saving with the in-engine save/load feature, it throws an error writing "transmissiveness" to an object which doesn't exist (null)?

    Weirdly enough, for me, the problem seems to only occur if my game adding a simple object into the game on start up? It doesn't have any behaviors attached to it but without fail if I add it to the game after start up, the saving crashes.

    And to clarify, it still is happening in this hotfix build!

    That said, I am rooting for the cool 3d features! I'd love to try my hand at a 3d game in the future with construct <3

    • I'm having the same issue. My game uses the save feature when initializing a layout so I just get a black frozen screen when testing. Definitely need this patched since my game is completely broken in the current version.

      The game runs when I disable the save action. It also runs when I disable the creation of some objects that happen just after the save action. So it has something to do with saving and object creation together.

    • I also encountered a bug in the save function after updating the engine to the latest R506.2 version—whenever I click to save the game, it freezes and becomes unresponsive. This issue has not been fixed yet.

  • As I said in the previous version topic, there's still a crach with the "save" action.

  • I also encountered a bug in the save function after updating the engine to the latest R506.2 version—whenever I click to save the game, it freezes and becomes unresponsive. This issue has not been fixed yet.

  • Instead of exporting to Steam, it now seems to export for remote viewing.

  • I also have a blocking problem with the saving feature.

    If I try to save my game, the game freezes and I have to Alt+F4. If I try to load a game, I have a black screen and it freezes too.

    I wanted to make a last update to my demo before Steam Next Fest wich is tomorrow but I can't, I have to leave the version already on Steam even though I'm not currently happy with it. And I'm supposed to release my project in a few weeks and that's a bigger problem even.

    I've tried using R495.2 to continue working with the older version of Construct bet weirdly, I have a black screen when launching my tutorial wich never happened before. You don't seem to have a backward comptability.

    So I'm helpless until the bug is fixed. It's a 6.5 years project and I'm about to miss the launch, could you fix it ASAP please ?
