  3. foliage for Unreal Engine

    Hi Mark,

     

    did you found a good way to export growfx stuff and import it to the unreal engine? I'm very interested in that. Also poly count info if you know something about.

     

    greetings

    Ben

     

    Hi Ben

     

    Good timing. I'd been doing other things, but I'm just about to start up again. I'm still trying to figure out the best solution for the particular tree I'm doing. It has clumps of blossom, so it's a liitle trickier than leaves to get looking good.

     

    I took a look at some of the assets in the marketplace. I'm sorry, I can't remember the exact numbers, but if you're going to use many trees in a scene, as few polys as possible. It's still not at the stage where you can go crazy. If it's a hero tree, then you can up the number. Export is just FBX of the whole tree.

     

    In the end, I decided to just get the trunk and main branches out of GrowFX and model the smaller branches, leaves and blossom seperately, although you could do them in GrowFX too. The poly count really jumps if you do smaller branches with meshes, even if you reduce the detail. The solution is to make some variants as meshes, bake them onto planes and position them as naturally as possible. Not GrowFX, but here are some of the links I'm using as reference. Also please let me know if you find anything useful!

  5. foliage for Unreal Engine

    in For technical questions

    Posted

    Hi

    I wondered if anybody would be willing to share tips for creating foliage for Unreal Engine.

    I'm about to start off experimenting. I'm concerned about ...

     

    1. total poly count
    2. whether to use meshes or opacity mapped leaves
    3. how I should set up groups of leaves and branches so they're easy to deal with and efficient in UE

     

    Thanks.

    Mark

     

     

     

  11. cosmos branches

    in For technical questions

    Posted

    I'd appreciate some help getting Cosmos branches right.

     

    I have a main stem. From one point, there are two branches at 180 degrees to each other. At the next point up the stem, there are two more branches at 180 degrees to each other but at 90 degrees in relation to the pair above and below. That continues up the main stem.

     

    How do I do this? Can I do it with one distributor, or will I need two?

     

    Thanks

  16. affects curves giving unexpected results

    Hi Eduard

    Thanks. I appreciate the help.

     

    Actually, my problem was solved with your last advice, although I'm still not sure what I could use "Parameter: Path position" for.

    I was just wondering if there was a setting equivalent to the Path distributor Range parameters also in the Path position distributor, but it looks like there are only discrete values you can set?

     

    Please excuse all the questions.

    I'd really like to master GrowFX.

    Hi Eduard

     

    Thanks for the very easy-to-understand screenshot.

    I've attached a file.

     

    How can I spread the distribution of the branches along the length of each level for "DenseBamboo_01"? In this case, I probably don't have to do it, but I'm curious and I can't find the appropriate setting.

     

    For "DenseBamboo_002", I've returned the setting to "Parameter: Path position". I thought that "Calculate all levels" meant consider all levels as a whole, but reading Help again, it looks like that's not it. Can you give me an example of how I would use this setting?

     

    Thank you!

    Mark

    Thanks!

    So I needed to use "Parameter: levels", not "Parameter: Path position".

     

    I have a couple of questions, if that's ok.

     

    1. Won't using "Parameter: levels" mean that for each level there will be only one length calculated? So all the branches coming out of level 1 will be the same length, all those from level 2 the same length etc?

     

    2. What was the problem with the way I was doing it? The explanation in the Help file seems to suggest that it's possible.

     

    Thank you

    Hi

     

    I'm having trouble figuring out the affects curves.

     

    In the attached file, from the "Trunks" path Parameter:Length I'm trying to affect Branches->Length and also the density of the "strings" path. The length of the branches doesn't seem to be following the curve at all. I'd like the "strings" paths to start at about a quarter of the way up the total length of the object. Can't seem to get that working either.

     

    Am I misinterpreting the curves function? Is there a better way to do this?

    I apologise if I'm missing something obvious.

     

    Thanks!

    MInd if I resurrect this topic?

     

    With your single distribution path Eduard, I was wondering if there was any way to have a more steps around the bamboo joints and less in the straight sections. I need more detail around the joints.

     

    Thanks

    Mark
