Amazing & Beautifull, nice job!!! 
May we see the code? its OpenSource? Where can i play it? I love harvest moon and your game its a huge oportunity to make my own version? what you think? i could help you with the models...let me join? i use blender and .b3d too.

Re: :)
thanks for the comment, the game is done yet still alot of work to do.grayman wrote:Amazing & Beautifull, nice job!!!
yes, i will release some code, for this beloved irrlicht forum.
to be honest
those dirty code still need a lot of optimization, and we (my team) are just one programer, one 3d artist, 2 marketing guy, and one web programer.... thats alot of work....
we are optimis to build a game and maybe sell it. starting a small game studio called HOM3. as it is a verry begining we working with no sallary. Just work hard to finish it as fast as we must. are you sure still wanna join?

i made a custom class to render grasses. here is the screen shoot
i've got some problem here. i think it is about Z_Sorting, and i fix it with register the scene node with ESNRP_TRANSPARENT and set parameter ALLOW_ZWRITE_ON_TRANSPARENT, but another problem occure.
from one side
from the other side
1. as you can see, those grass not properly z sorted, any one ever experience this? how can i solve this?
2. and one more thing, why setMaterialTexture, setMaterialFlag, and setMaterialType didn't change my custome scene node ?
here i post my code
CTerrainGrassNode.h
CTerrainGrassNode.cpp
please help this one is very annoying

This looks really good, keep it up and don't give up, I aim to get my game "Deep Sleep" selling one day, maybe even in shops 
it's hard and you always come across obstacles but don't gice up!

i've use the const qualifier, and now it works.hybrid wrote:You didn't use the proper function qualifiers, getMaterialCount needs to be const.
Try to use the ALPHA_REF material for leafs and grass.
but i don't understand what is this ALPHA_REF, i didn't found it in the API documentation, so it is not a scene parameter and not a material flag... so what is it?

after being busy for several weeks now i great fully thank my beloved forum for the snippets and tutorials that really help me in developing this editor. this editor will help my artists to build models and watch them, how they gonna look like in the game. here's some screen shoot
1. terrain blending, creates grass ground or sand.
2. terrain sculpting, to make hills, islands or river.
