Is Progressive Lightmapper better than Octane ?

    I have seen than Unreal now has Vray support for creating real to life archviz projects.

    As I haven't used Octane and Progressive lighmapper is still a work in progress I wonder if Octane can produce better real to life visual results than Progressive Lightmapper.

    Thanks

    Octane is an offline renderer extension while progressive lightmapper is a lightmapping backend. Those two are very different tools for very different purposes.

    I know what octane is. I wonder if it can be used like Vray in Unreal that they can bake texture too.

    According to this blog post - https://blogs.unity3d.com/2018/03/22/octanerender-for-unity-update/ - seems like you can. Can't comment about its functionality further, as we did not develop this plugin ourselves. Please contact OTOY if you'd need more information.

    Based on the user feedback all over the internet (see the asset store here for example) I thank that it's safe to say that you shouldn't even bother with Octane at all (it simply doesn't work and OTOY never fixed it since release a year ago...which isn't really surprising given OTOY's track record anyway..)

    To bad. I do not want to move back to Unreal for archviz because of vray support.

    Tbh I have tried it in Unity 2018 and it works fine for me. The basic reaytasing at least, I have no idea about baking lightmaps or other features though. Also I'd like to say I have a pretty old video card and a I5 computer, rendering is slow yes...

    I'd recommend taking a look at Deckard Render, the author has a good history with his packages and while I haven't tried it myself yet it looks like a fairly straightforward way of rendering out from Unity in great quality.

    Thanks for your feedback. Apparently, I cannot use Deckard Render as I need to bake photorealistic textures on objects.

    The developer notes that Deckard doesn't render in realtime and is suited only for exporting images or movies.
    Have a look at this video. The quality of baking lightmaps from VRAY in Unreal has that result. It is nearer to reality without needing to spend so many hours to accomplish that result.



    Here it the explanation in detail https://docs.chaosgroup.com/display/VRAYUNREAL/V-Ray+Bake

    As I am working alone most of the time is a huge time saver for having better results without needing to tweak materials and all other aspects for making it look more realistic.

    I hope to find a tool that has a similar output for unity and be able to bake lightmaps but Otoy seems not to be interested in that and octane had another great disadvantage that is tight in Nvidia hardware only for baking.

    Unity's GPU lightmapper is based on AMD RadeonRays technology. I wonder why they are not building that feature to archive similar results with VRAY + Unreal in baking.

    https://www.amd.com/en/technologies/radeon-rays

    That would make unity one of the best tools for ArchViz, Visualization and VR.

    There is a path tracer in the works.

    Good news. Do you know if we will see a demo this year ?
