Hello fellow gamedev!

JAre you ready for a tutorial featuring Lech from Eco Tales?
Whatever the answer, here it is!

I’ve recently started to dabble into Houdini and to my surprise, there aren’t that many tutorials out there on using it for game development.

So, being totally in love with my own voice and an ex-teacher I figured, why not create some?

There are plenty of getting started tutorials out there so the ones I’ll be recording will mostly be around whatever I fund useful in my daily Unity and Unreal work.

First up is a short video on getting pre-fractured rigid body animations into Unity, check it out!

I accidentally cut out the FBX-export from that video, so here’s a Quick Tip on how to do that.

Using attributes doesn’t work with FBX-files, so in this video we look at how we add working material slots to the fractured mesh.

Here’s the link to the Houdini Gamedev Tools.

There is an outdated version on getting one into Unreal which I might create a new version of soon, unless the original author does, so make sure to subscribe to my youtube channel and write a comment if you find the thought alluring!

Tjipp och Hej as we say in Sweden

Look up there, the wonderful sunshine, that the boys had better see nothing of!

I don’t think they are to be honest, things are actually starting to take shape, who knew that “Houdini” could be such a time saver?

J Much like Lech I’m amazed at how amazing Houdini is as a generator of things, after countless tutorials I’m starting to get the hang of it, finally!


That’s the start of a mushroom grower! Ok, so I accidentally didn’t save and then it vanished in a crash with this… Now as I’m writing this, I remember that there are auto saves! I’ve gotta check that folder! More on that next week.

Let’s take a look at the wall that I’ve shown off in earlier recaps.


I agree, it doesn’t look very good, at all, but now it contains everything needed for a finished game asset, let’s walk through the elements.

First of, there’s visible geometry, we have walls with columns and some rocks, all of these are completely procedural and are created based upon a single curve, you know how fast you can draw a curve? Seconds, literally! Editing it is just as easy and quick!

Secondly, see those light green lines within the walls? Those are colliders, these are generated from the walls and heavily reduced in precision (read as poly amount) to make collisions less costly.


As you can see above, the same goes for the rocks.


Third we’ve got the materials, the wall and columns are auto UV unwrapped and painted with vertex colors, the shader in the case of these walls blend up to three different textures spread over red, green and blue. The UVs are actually world space dependent so the texel size will be constant across all elements, I’ve changed the material tiling here to make them stand out a bit more.


Now let’s look at the rocks again, for UV-mapping them is on a whole new level of difficult, they’re all randomized and as you can see, their shapes are hugely varied!

Let’s take a look at the UVs.


As you might be able to tell, these are just slapped on using an orthographic plane projection, why then, do the rocks not look like



Well, while I in the future would like to try and create pelt-maps based upon a seam created from the Y intersection plane from my terrain, I in this case wrote a simple tri-planar shader, which uses two textures (but three samplers) for left/right, front/back and top/bottom texture projection based upon world space normals.

I’ve created a version of it in Shader Forge which you can download here, you may use it in any project, including commercial ones, as long as you like Eco Tales on Facebook!

That’s all for me this week, next week will be all work! Which for me means all play! I love game development!

K Well I sure didn’t see any sun on my vacation to Gotland visiting family, eating ice cream and going to the beach as I had my shades on the entire time. I do suspect Mr Lech knew though and brought forward an evil plan to prevent me doing this again as I know have a cold on my first day back to spend time on Eco Tales.

Now I have a week or two before work starts and I’m devoting it entirely to Eco Tales, well… It would be nice to get at least one role playing session if I can drag Jona from Houdini, it’s been way too long since we played last. Anyways, I’m starting  of my week by doing a few 3d prints, same model and pose as before but larger just to get the hang of it before Jona takes the huge amount of time it takes to prepare another model / pose.

Besides that I’m hoping we can finalize the webpage as you might have noticed changed before our vacation started.

Hello Eco Talers!

Yes, that’s we’re calling you, at least in this post, we’re back from our vacation in Japan, once again, we didn’t go together, that would’ve led to nothing but Eco talk after all!

That's not to say we didn't meet at all in Japan.

That’s not to say we didn’t meet at all in Japan, here’s a semi-selfie from the inside of an elevator!


The boys… The boys are back! Not that I’m any way happy or touched by that.

JAlright! (Finally?) Back to reality, Japan was amazing, however, I couldn’t help watching Houdini tutorials all night long in antecipation of getting back to Eco Tales!

Long story short, I went out to some seriously amazing Japanese forests to gather references and inspiration, take a gander at this small collage of a temple forest on the outskirts of Kyoto!


Images won’t do it justice, but here’s my attempt!

Over and out, K is next!

K Here I sit, jet lagged and already missing Japan but luckily I have Eco Tales to look forward too.

It has been twelve years since my last long trip which took place in China (usually I just travel for a few days every now and then) and this time I got to go to awesome Japan with my partner Linda and had the fortune to meet up with my ever so fabulous co-developer Jona.

Tired from walking the great wall back in 2004.

On The great wall back in 2004

So stretching twelve days I’ve seen Osaka, Kyoto and Tokyo, from the bambu forest to the sprawling mega city with it’s many skyscrapers. Japan sure has a lot to offer, from the best service minded, helpful and nice people, great food (and sometimes great food that I just can’t eat because it’s weird), and always something interesting to see when you just walk about, something I did plenty of, according to my Fitbit I took on average some 26 000 steps each day something I gladly celebrated with some Chocolate Pocky.

So Japan is beyond awesome and KJ Interactive should relocate there but no time for day dreaming, there is lots to do on our wonderful game Eco Tales: My Item Shop.

Hello KJ-lovers!

We’re on vacation in Japan and so the weekly updates are on hold, we’re not together! It’s just a strange coincidence.


They… Went… On vacation! It’s as if they don’t care about me or you at all!

Well, done is done, I’ll make them work extra hard, you can count on that.

While you wait for us to come back, like the facebook page!

You don’t want to miss the return of KJ!
