Unwanted change in landscape.node file

[renato.semadeni]

Hi there

 

Everytime I change something in the washington scenery, adding an object for example and then save my changes, I observe a drop in performance about 50%. I track it down, that the landscape.node file is changed in the following lines:

 

Old entry in the landscape node file:

<surface name="terrain" material="terrain" property="surface_base">
<material>
	<state name="terrain">1</state>
	<state name="detail_0">1</state>
	<state name="detail_1">1</state>
	<state name="detail_2">1</state>
</material>

New entry in the landscape node file:

<surface name="terrain" cast_shadow="0" cast_world_shadow="0" intersection_mask="256" material="terrain" property="surface_base">
 <material>
        <state name="detail_0">1</state>
        <state name="detail_1">1</state>
</material>

But I don't change anything on the world shadows.

 

Thanks in advance

Renato

Hi Renato,

 

Thank you for detailed description!

 

Washington demo have outdated engine binaries (November, 2013) and it is possible that not all functions are working without problems. I will check this behavior with the newest engine version (internal September builds) and report back. 

 

If I understand you correctly, reproductions steps are:

1. Launch Washington demo with washington.py (-extern_define string is empty);
2. In the Unigine Editor add any object into the world (mesh / node);
3. Save world;
4. Check for modifications of landscape.node.

Sorry for the inconvenience caused.

Hi Silent

 

Thanks a lot, and yes the reproductions steps are exactly as you described.

Hi Renato,

 

Good news - I can't reproduce this behavior with the latest engine version (and latest Washington version). Bad news is that we cannot provide a fix to this issue for the old Washington version.

 

We will double check this behavior before the Washington demo update.

 

Sorry for the inconvenience.
